How is the diameter of the bronchioles controlled? Smooth muscle

How does the pressure in the thoracic cavity change during inhalation and exhalation? • Inhalation- pressure decreases below atmospheric pressure • Exhalation- pressure increases below atmospheric pressure

What is the definition of the following? • Total lung capacity- max air lungs can hold (VC + RV) • Vital capacity- max air in and out of lungs (TV+ IRV + ERV) • Residual volume- amount of air always in lungs • Inspiratory reserve volume- amount of air inhaled after normal inhalation • Expiratory reserve volume- amount of air exhaled after normal exhalation

Urinary System

What are the functions of the kidney? How does the kidney carry out these functions?
Removes waste and regulates volume of solute concentrations, regulates blood pH, conserves water, produces red blood cells, activates vitamin D

What is the nephron? Functional unit of kidney

What is dialysis and CAPD? • Dialysis- use of artificial devices to cleanse the blood of wastes and excess fluid • CAPD- home filtering system that goes through the abdomen

Digestive System

What are the organs in which food travels as it is digested? What occurs in each? • Mouth- teeth do mechanical digestion and turn into bolus, tongue helps with swallowing and taste and quality; contains salivary gland • Esophagus- peristalsis • Stomach- storage of food (2-3 hours); liquidation of food (bolus turns to chyme); chemical digestion of protein (pepsins) and HCL destroys pathogens • Small intestine- digestion and absorption • Large Intestine- food enters as a liquid; water is removed and waste becomes solid; fiber feeds bacteria that live in large intestine

What are the accessory organs? What do they do? • Salivary glands- in mouth, moistens food and contain salivary amylase which digests carbohydrates in mouth • Pharynx- voluntary (tongue pushes bolus to back) and involuntary swallowing • Liver- fat digestion; examines blood after reabsorption- portal system • Gallbladder- stores bile • Pancreas- secretes enzyme for chemical digestion

What are the four layers of the digestive organs? What is within each of the layers? • Mucosa- mucus • Submucosa- blood vessels • Muscularis- muscles • Serosa- fluid to prevent friction
Where does mechanical digestion occur? Mouth and stomach
Where does chemical digestion occur of carbohydrates, proteins, and lipids? What enzymes are responsible for digesting each of these substances? • Carbohydrates- salivary amylase from salivary glad; Amylase from the pancreas; Maltase, Lactase, & Sucrase from the small intestine • Proteins- pepsin in the stomach; Aminopeptidase from small intestine; Trypsin, Chymotrypsin, & Carbozypeptidase from the pancreas • Lipids- Lipase from the pancreas

Where does the food become bolus and where does it become chyme? Bolus-mouth; chyme- stomach At which point is it called waste? Large intestine

What is peristalsis? Muscular contraction to help propel food

What 3 things are secreted in the stomach? What is the purpose of each? • Mucus- protects stomach from acid • Pepsinogen- inactive form of pepsin (activated by HCL), digests protein • HCL- destroys pathogens

Where does absorption take place? How is this organ designed for absorption? Small intestine; it is folded to increase the amount of time chyme is in the SI for absorption

What is the function of the portal system? Where is it located? Located between liver and small intestine; as we absorb nutrients blood gets carried to the liver and examine for toxins and level of blood glucose

What causes diarrhea and constipation?
Diarrhea- waste moves through large intestine too fast
Constipation- waste moves through large intestine too slow

Reproductive System

What is the function of the… • Testes- production of sperm • Epididymis- maturation of sperm • Vas Deferens- carries sperm to urethra • Prostate Gland-produces alkaline • Seminal Vesicles- fructose for energy and amino acids to thicken sperm • Bulbourethral Glands- rinses trace amounts of urine from urethra • Ovary- produces estrogen and progesterone; produces eggs • Oviduct- carries egg to uterus; place of fertilization • Uterus- development of baby • Vagina- birth canal

Where does spermatogenesis occur? Seminiferous glands in the testes

What separates to form primary spermatocytes, secondary spermatocytes, and spermatids? How many chromosomes does each contain and how many members of the homologous pair are in each? • Primary spermatocytes- Spermatogonium; 46 chromosomes diploid • Secondary spermatocytes- 46 chromosomes haploid; homologous chromosomes separate • Spermatids- 23 chromosomes and haploid; sister chromatids split to form them

What are the 4 parts of the mature sperm? • Acrosome- enzyme for penetrating egg membrane • Middle piece- mitochondria for energy production • Tail- mobility • Head- chromosomes

How is the level of testosterone and sperm production regulated? • Lutenizing Hormone- stimulates the production of testosterone • Inhibin- decreases the production of testosterone • Follicle Stimulating Hormone- increases production of sperm by making seminiferous tubules more sensitive to testosterone

What morphological changes take place in the ovary and uterus during each menstrual cycle? Uterine lining thickens and ovary releases egg

What is the function of the follicle cells and the corpus luteum? • Follicle cells- surround primary oocyte; at puberty, they divide to form layers of cells and secrete a fluid that contains estrogen • Corpus luteum- secretes progesterone and estrogen to maintain pregnancy in beginning until placenta is formed

What is the level of estrogen and progesterone during each phase of the cycle? • First 5 days- estrogen and progesterone at lowest level • Follicle Maturation- (days 6-13) estrogen levels continue to increase • Ovulation- (day 14) high levels of estrogen • Uterine Lining Maturation- (days 15-28) estrogen decreases slightly, progesterone increases
What is the function of estrogen and progesterone? • Estrogen- causes maturation of mature follicle, high levels cause LH release • Progesterone- maintains uterine lining

What hormone stimulates the production of estrogen? Follicle Stimulating Hormone
What hormone causes ovulation? Lutenizing Hormone

When does each mitotic and meiotic division occur in order to form the egg?
Before Birth- oogonium splits by mitosis to primary oocyte (46 diploid)
Puberty- homologous chromosomes separate to Secondary oocyte + 1 polar body (24 haploid); sister chromatids separate to Ovum + 3 polar bodies (23 haploid)

How many eggs are formed compared to how many sperm are formed in the male? Males have 4 spermatids while females have 1 egg and 3 polar bodies

What happens to the level of estrogen and progesterone if the egg is fertilized? Why? Progesterone and estrogen levels remain high to maintain uterine lining

How do birth control pills and progesterone shots block conception? Maintain high levels of estrogen/progesterone to inhibit FHS release then no ovulation

What are the three stages of syphilis? • Stage 1- 2-8 weeks chancre develops and lasts few weeks • Stage 2- rash develops weeks to months after chancre disappears • Stage 3- gummas develop months-years after rash disappears and death is likely

Why are STDs often not diagnosed in women until later stages? It is in the PDI in females and UTI in males; live in uterus

What cells does the HIV virus infect? T-cells
What are the stages of HIV infection and the symptoms of each? • Initial Infection- virus replicating but very mild symptoms; high T-cells • Asymptomatic Stage- T-cell destruction = T-cell production; HIV virus “hiding” • Initial Disease Symptoms- wasting syndrome (lose 10% body weight), swollen lymph nodes, neurological symptoms • Early Immune Failure- Thrush (yeast infection in mouth), Shingles (chicken pox) • AIDS- low helper T cell count, opportunistic infections, >10% loss of body weight, dementia

Genetics:

Define the following: • Gene- segments of DNA, code for specific protein • Trait- results from the action of one or more protein • Allele- alternate form of a gene located on a specific site of a specific chromosome • Homozygous- same allele from each parent • Heterozygous- different alleles of the same gene • Genotype- the alleles that are present; the genetic composition of an individual • Phenotype- the observable physical traits of an individual • Law of segregation- during gamete formation, the two alleles separate; occurs when homologous chromosomes separate to form secondary spermatocyte or oocyte • Dominate genetic disorder- homozygous dominant and heterozygous individuals have the disorder; one parent has the disorder • Recessive genetic disorder- requires two recessive alleles to have the disorder; someone who displays the dominant phenotype but is heterozygous for a trait that is a carrier of the recessive allele • Sex-linked genetic disorder- most genes on the X chromosome have no corresponding alleles on the Y chromosome (known as X-linked genes); more common in males (XY) • Sex-influenced genetic traits- autosomal genes whose expression is influenced by sex hormones; ex: baldness is more common in males • Nondisjunction- homologous chromosomes do not separate evenly; causes down syndrome

...usage of animals. Animals do not belong in a zoo for personal visual enjoyment. Almost every child has taken a trip to the zoo. At the zoo we see different animals in created habitats eating prepared food. A variety of different animals are either captured or born to amuse humans for a profit. The rights of freedom stripped from animals to make us smile are not essential to our survival. Animal’s that are raised outside their natural habitat cannot survive among their fellow species in the wild. The Zoo and the circus are prime examples of animals misuse and abuse. Animals from the zoo and circus would not be able to coexist due the difference in freedom. Less animal attacks would occur as well. Zoo’s and Circus’s argue that they save endangered species and educate the public, but I strongly believe the costs outweigh the benefits, and individual animal’s rights are violated and unjust. Zoos define themselves as bringing people and animals together, as well as educate the public with the appreciation of the animals. This exposure and education motivates people to protect the animals as they believe. Zoos save endangered species by bringing them into a secure environment, where they are protected from predators, habitat loss, and starvation. Many zoos also have breeding programs for endangered species. In the wild, these animals can find it hard to locate mates and reproduce. Reputable zoos are accredited by the Association of Zoos and Aquariums (1994), and are held to high standards...

...Zoos are Inhumane Camps for Animals Wild animals are just that; wild. For centuries humans have taken wild animals out of their habitats and put them in captivity. There are many reasons behind this act, some being protection from predators, disease, and possible extinction. Individuals maintain that zoos are a way for youngsters and adults to attain education about animals. The animals are well cared for, maintained, and fed regularly. People are the biggest danger towards animals that live in the wild. Certain species such as African Elephants are hunted for their tusks, minks for their fur, bears for their pelts, and Mediterranean monk seals merely because they eat all the fish. There are several other animals and mammals that are either severely endangered or extinct. With that, zoologists and others seem to think it is better to have species such as these kept captive in a zoo. Zoos are a means of entertainment in addition to a safe haven for animals that are in danger. “Both the Baltimore Zoo and the Detroit Zoo have taken in polar bears rescued from a traveling circus, and the Bronx Zoo took in an orphaned snow leopard from Pakistan in 2007. The cub, Leo, now spends his time frolicking and chasing small animals that wander into his enclosure” (Nancie Majkowski, ver. 2). On the rebuttal side, zoos are believed to be inhumane camps merely for the enjoyment of spectators and for cities to make a buck. There are several organizations that demand the release...

Giza Zoo

...MONTH: March 2008 Could the Giza Zoo become a rescue center?   CAIRO--Little changed in 117 years, the Giza Zoo is either the best of zoos or the worst of zoos, according to many noisy authorities, and may actually be a bit of both. The animal collection is distinctly idiosyncratic and of little value from a conservation perspective, since most of the examples of rare species represent inbred genetic lines. Yet the zoo does include enough lions, elephants, hippos, zebras, giraffes, and monkeys to satisfy most visitors. The animal care attracts far more complaints than the variety. Much ridiculed by non-Egyptians, the exhibits of Rottweilers, Dobermans, German shepherds, and other dog breeds are of interest, albeit apparently declining, in a society where keeping pet dogs is still rare, cold climate breeds are seldom seen, and most dogs are rat-catchers and scavengers. People, many of them elderly, who might never keep a dog from fear of landlord hostility or social ostracism come to feed and pet the zoo dogs. Most of the Giza Zoo is a gathering place for teenagers, but the quiet corner housing the dogs, ducks, and geese is something of a senior center. The Giza Zoo is among the more enduring works of Khedive Ismail, who at age 33 in 1863 inherited the governance of Egypt as senior 
representative of the Turkish-based Ottoman Empire. Khedive Ismail in 1869 opened the Suez Canal, 10 years after a French corporation began digging it, and in 1875 turned the canal over to the...

Invesigate Science at Work

...Research We received a task which was to investigate science at work. This would vary from many different fields in science meaning that there are many different options which are available to us across the U.K. Due to this, we decided to narrow the search to local companies so that finding information from them was easier to attain due to them being easily accessible. So, to do narrow the companies to make it easier to find the companies and group them; 1. Firstly, before anything, sat with my peers and teachers and came up with different sectors of what companies would have aspects of sciences which are used and then we created the groups to specific aspects of sciences such as Health, Food, farming, education, manufacturing etc. We chose these types of sectors due to them being specific to a type of science which would split the companies due to the different uses of what the comp 2. .anies focus on. As we created the groups, we made sure that our groups were such of those that can be linked with each other. 3. After doing so, we then brainstormed on what the company types would fit under the categories we created. This was done on a mind map so that we could see the groups and what type of company or what the company specializes in would be visible to us after we had found the types of companies we were looking for, we could then find the companies that were close to us. We were looking for the companies that were near us due to them being easily accessible...

Zoos Are Prisons

...Argument Essay Comp I April 16, 2014 Zoos are Prisons When I was a child I loved going to the oversized Fort Worth Zoo, but now I am older and more aware of the truth about zoos. To the general public, zoos give the impression that they are there to educate and preserve endangered animals while performing beneficial research, but that is not entirely true. The actual truth behind the scenes of most zoos, not all zoos, is very sad and ugly. I will never visit or support another zoo now that I am aware of how those animals have to live when kept in captivity. Zoos are prisons for wild and exotic animals that deserve to be free. The first reason I am against zoos is because of the fact that they are not fully committed to the well-being of the wild and exotic animals they inhabit. I agree with the “Last Chance for Animals Organization” when they said, “While zoos claim to provide conservation, education, and entertainment, their primary goal is to sustain public support in order to increase profits” (“Zoos”). It is a fact that many zoos are aware that baby animals attract crowds so they breed their animals frequently for the sole purpose of making more money (“Animal”). Once these cute babies start to grow up, zoos very sadly begin to discard of them in various ways (“Zoos”). This only shows that zoos are in fact putting profit, entertainment, and the creation of new attractions above the well-being of their animals. Zoos are also guilty of choosing big animals that...

Animal Rights Speech

...speaker tonight has voiced her opinions numerous times in the last year on one specific heartbreaking case. Although in North America there are many laws pertaining to animal welfare, these do not spread around the globe. Cruelty to animals in captivity can include neglect that is so monstrous (ie withholding food water and the need of natural habitat) that the animal has suffered physically or psychologically, died or has been put in imminent danger of death. In North America there are over 500 accredited zoos. Each one has gone through numerous health code regulations as well as random check ins from the SPCA. Animal welfare codes are constantly changing and zoos in Canada and the United States must adhere to the changes. If we look at our local zoo in Winnipeg, The Assiniboine Park Zoo, they recently made a multimillion dollar upgrade to their polar bear exhibit. This upgrade didn’t come out of the blue, the city of Winnipeg decided to fund the upgrade after the zoo failed to meet the new polar bear enclosure regulations. The new enclosure is home to 4 bears, but last January it sent and invitation out for a new resident. Perhaps the most talked about case of animal cruelty of the decade is that of Arturo the polar bear. It was November of last year when our guest speaker first tweeted about the tragic case of Arturo.

Seaworld: People For The Ethical Treatment Of Animals

...Ever since animals are manipulated for greedy people. Making revenues their priority and not the effect of their actions. Animals do not live solely for people’s entertainment and institutions similar to SeaWorld have taken orcas from their natural habitat and held them captive for “tricks”, endangering these creatures’ lives, therefore we should boycott these businesses that contributed to the unjust treatment of these animals. SeaWorld have held animals captive in small tanks for their own selfish reasons. Forcing orcas to entertain visitors for food. Even orcas with serious illnesses are to perform tricks in front of an audience. Animals held captive for a long time will create a serious effect on them. Displaying aggressiveness toward their trainers resulting to accidents. These animals are supposed to be in the wild where they can roam free. Tanks with concrete walls cannot compensate for their needs. This causes orcas to die with stress-related problems. Ever since 1971, at least 37 orcas have died and 30 orcas remain captive because of SeaWorld. None of the orcas died in their hands because of old age whereas orcas live an average of 30-50 years. PETA, People for the Ethical Treatment of Animals, made the public aware of SeaWorld’s horrifying actions. They repeatedly kept telling people not to support SeaWorld. Asking to never buy a ticket or visit their parks to help the animals held captive. PETA created different campaigns, petitions and even protested. Hoping their...

Do Elephants Belong In Zoos Summary

...I would argue the article “Do Elephants Belong in Zoos?” by Jeffery P. Cohn is effective because he employs pathos to move his audience to action, he presents evidence in a logical way, and he fairly evaluates counter arguments. The article first starts out by saying how elephants in zoo captivity do not have enough space to roam around. Then it goes into how zoos are getting rid of their elephants, because they don't have enough space and the visitors are getting very upset that they don't have elephants anymore. Once they get rid of their elephants, they are trying to make upgrades to the elephants’ sanctuaries to have a bigger space and make it feel as if they were still in the wild. One of the main arguments that I think makes this article effective is how the elephants don't have enough room to get the amount of exercise needed to stay healthy. In the article, the author states “They walk up to 50 miles a day. When they don’t move that’s when they have physical problems” (Cohn 715). Elephants do need exercise to stay fit, because they are large mammals. There are many zoos out there right now that are making their elephant sanctuaries large. They are spending an abundance of money to get these sanctuaries up to date so that elephants can live longer in captivity. They are making a “$38 million, 3.7-acer elephant...

Tantulas Research Paper

... Tarantulas How long tarantulas live and their behavior are very interesting. Their not like just any spider. Female tarantulas can live thirty years or longer in the wild. Even in captivity, they have been known to live for over twenty years. Although on the other hand, males have a life span of just five to ten years on average. Now tarantulas do come in many sizes. The largest tarantulas have a leg span of nearly ten inches, or about the size of a dinner plate. This does however depend on the size of your dinner plate. Tarantulas are docile(ready to accept control or instructions) and rarely bite people. Tarantulas only attack when they feel threatened. However when they are threatened, they defend themselves by throwing needle like barbed hairs at their attackers. Tarantulas can feel threatened simply by being touched the wrong way or being held the wrong way by a human. They use their hind legs to scrape barbed hairs from its abdomen and flings them in the direction of the threat. How tarantulas catch their food and what they eat seem strange. Although this also may sound like a good way to get food, it’s not. Tarantulas ambush small prey at night, stealthily sneaking up on a potential meal and then pouncing. Tarantulas paralyze their prey with venom, then use digestive enzymes to turn the meal into a soupy liquid. Tarantulas will eat anything small enough to catch and consume. They will eat things things such as: arthropods, reptiles, amphibians, birds, and even small...

I believe that zoos are one of the ways to safe the instict of animals who are in danger. Opponents of constraint animals in zoos argue that it is against the nature to prison animals in small cages, which deters their natural capabilities, as a result they are emotionally weak as compared to the wild animals in jungles. It is also believed, that caged animals are presented as an entertainment to people who come to visit the zoos. Therefore, these animals have to be there all the time to entertain which can be the reason of their lack in sleep and diet and lead them to be sick. However, I am unconvinced that zoos should be banned....

The Pros And Cons Of Animal Captivity

...Animal captivity is the case in which animals live under human care. Animals in captivity do not have as much freedom as those in the wild. Animal captivity is common in farms, private homes, zoos and laboratories. These places domesticate the animals either for sentimental or scientific reasons. In short, animals should not be kept in captivity because it is morally wrong and alters the evolution process of natural selection. Animal captivity is morally wrong. All animals, including humans, exist with their own evolutionary motives to reproduce and prosper. Humans should not interfere with this process by taking animals out of their natural habitat. When they are domesticated, it is also much more likely to be cruel to them. For example,...

Are Zoos Inhumane

...Zoos are a popular place to visit, but according to research, zoos are in fact not what they seem to be. According to research zoos are proven to be inhumane. Researchers say that the animal’s enclosures are too small and they’re unhygienic. Also zookeepers are mean to the animals. Zoos are not suitable education tools, zoos are unethical. Not all zoos are bad, but this research shows the downside of zoos. In addition to these facts, this paper will provide an in depth look at zoos. One reason that proves that zoos are inhumane is that their enclosures are too small. One researcher said that the enclosures are “1000 times smaller than their natural habitats” (Pomeroy).

Animal Captivity Research Paper

...You have probably been to a zoo before, but there are some things you may not know. This includes, animals being held captive, habitat change, and lack of food. In my opinion animals in zoos are not being treated properly. Animals should have the same amount of freedom as us, but instead they are being locked up in zoos their whole life. This has been going on since 1847 and has affected many animals lives in a negative way. Lets help change the future! Animals have been held captive since zoos have opened. APECSEC.org has informed me that this can cause high stress level of the animal. Another thing I have learned is when the animal is feeling trapped can cause aggression that is above normal. I have also learned from Zoos pro or con that animals should have the same right to be free as us and that we never realize that we are trapping animals for our entertainment. We are getting entertained while the animals are most likely bored in those small cages. Some people even believe that animals are being abused by zoos....
