...Sheep's heart dissection Lab report Introduction: In this lab, we examined the internal and external structures of a sheep heart. A heart is a muscular organ that pumps oxygenated blood throughout the body using the circulatory system. There me up to four chambers (as in mammals) which contain two atriums and two ventricles. A sheep being a mammal includes these qualities. A sheep's heart is made up of four chambers a left and right atrium, which are located in the upper chambers, are known as the receiving chambers, which receives deoxygenated blood. The lower...

...Heart Dissection I. Purpose The purpose of this lab was to practice dissection skills and to further our knowledge of the heart. From this lab we learnt about the parts and functions of the heart. For example, the different chambers, the veins, and the arteries that all run through the heart. Through careful observation we were able to identify all of the main parts of the heart that keep blood pumping through our body and were able to determine the important structures. Because of this lab I can successfully label a diagram and explain the use for each part of the heart. II. Procedure a. Materials i. Sheep Heart ii. Scalpel iii. Dissection Pan iv. Dissection Pins v. Tweezers vi. Gloves… (If you remember) vii. Camera for Pictures b. Procedure Because sheep hearts are so cheap and readily available, they are the most common use for this type of experiment. We began the lab by observing the external anatomy. We first observed that the heart did not have a pericardium. The pericardium is the body’s way of protecting the heart and separates it from the rest of the thoracic cavity. If it were present we would have cut it away to reveal the white lumpy tissue. The white lumpy tissue is fat tissue. The bulk of the heart tissue is the reddish brown muscle or myocardium. We placed the heart down showing the ventral side to reveal the following features: Apex, Superior Vena Cava, Inferior...

...Anatomy and Physiology Task 1 1. Discuss your dissection of the sheep heart and the cardiovascular system of the fetal pig by doing the following: a. Describe the similarities and differences between the fetal pig heart and the sheep heart. Differences: 1. Size 2. The left ventricular wall is thicker in the sheep than the fetal pig. Similarities: They both have 2 atria and 2 ventricles. b. Describe the four valves of the heart, including their name, location, and function. The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve: It is located between the right atria and the right ventricle. It is comprised of three “flap-like cusps” which when in its closed position, prevents the deoxygenated blood entering the heart from the body, from backing up in the right atrium from the right ventricle (regurgitation). http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows...

...2. Discuss your dissection of the respiratory system of the fetal pig by doing the following:DONE a. Compare the structure of the trachea to the structure of the esophagus. The trachea is along the mid-ventral portion of the neck in the thoracic cavity. It has horizontal bands. The esophagus is located and lies dorsal to the trachea and extends through the thorax on the left side. It does not have bands. b. Describe how the structures of the respiratory system (i.e., trachea, bronchi, and lungs) relate to their functions. The trachea has cartilage rings that support the trachea to keep the airway open. The trachea carries oxygen into the lungs via the bronchi. (Cont.) The bronchi transports air from the trachea to the lungs. The bronchi...

...Task 211.4.4-01-05, 07-09, 11 Nervous System Organization of Nerve Tissue Lab Exercise 1: The Multipolar Neuron A. What is the function of a neuron? Neurons carry and transmit electrical impulses generated by both internal and external stimuli. B. What is the difference between a neuron and a nerve? Neurons are the cells that exchange messages from the internal and external environments. Nerves consist of many neurons that transmit different signals to the brain. They form structural and functional units of the nervous system made up of neurons. C. What gives a multipolar neuron its name? It is named multipolar because of the multiple branches, processes, and extensions that stem off the cell bodies. D. What are the functions of the dendrites and axons? Dendrites receive incoming signals for the nerve cell. Axons carry outgoing signals of the cells to other cells in the body. Exercise 2: Structures of selected neurons A. Which slide contained bipolar neurons? The pyramidal cell slide. B. Which slide contained unipolar neurons? The dorsal root ganglion slide. C. What was unique about the dorsal root ganglion compared to the other two slides? The dorsal root ganglion was more round in shape compared to the perkinje and pyramidal cell slides.

...English 240 December 16, 2011 Should Animals be used for Research During the past ten years, a major controversy over the use of animals in biomedical and behavioral research has arisen. The debate about using animals for medical testing has been ongoing for years. The struggle is usually between animal rights activists and scientist. I believe that animal testing is imperative to the progression of medical cures, procedures and drugs. Scientists have been solving medical problems, developing new techniques and treatments, and curing diseases by using animals in biomedical research. Animal rights advocates believe that animals should not be exploited by humans, and that animals have the same rights as humans. Anti-vivisectionists oppose the use of animals in medical research. They believe that medical researchers are cruel and inhumane. Animal Welfare does not oppose all use of animals in research. They oppose inhumane and unnecessary use of animals and fight to eliminate pain and suffering of animals. On the Contrary, scientists argue that animal research is necessary because it helps them develop medications, vaccines, or new procedures to treat or prevent diseases for both humans and animals. Most research projects either do not involve pain or the pain is alleviated with analgesic or anesthetic drugs. They understand that pain causes stress for the animals, and this stress can seriously affect the results of the study. With all these controversies about this...

...objectives of the Circulatory System laboratory experiment included observing and learning to identify the structural characteristics, mostly arteries and veins, in the chest cavity of the fetal pig, which would further the understanding of the heart and lungs in most other mammals; another objective was to understand blood pressure and heart rate and the factors that affect it. The objectives of the Gas Exchange laboratory experiment was to observe the respiratory system in the fetal pigs, thus gaining an understanding of the respiratory system in most other mammals; another objective from the portion of the experiment that included measuring the respiratory volumes of humans and understanding the capacity of the human lung. Introduction There are two kinds of circulatory systems, an opened circulatory system and a closed circulatory system. The circulatory system is made up of an internal body fluid that is either hemolymph or blood, a pump system, and a vascular system that is made up of tubular vessels that move fluid from one location to another quickly(Dolphin 377). Hemolymph is the fluid found in the open circulatory system and blood is the fluid found in closed systems. In open circulatory systems the fluid leaves the heart through the arteries and returns through open sinuses rather than veins (379). Closed circulatory systems are found in vertebrates, their blood flow is within the blood vessels. The two types of closed systems are lymphatic and arterial. The...

...you be their voice? Lloyd biggle Jr. once stated “Life is life’s greatest gift. Guard the life of another creature as you would your own, because it is your own. On life’s scale of values, the smallest is no less precious to the creature who owns it than the largest.” Think about what that quote means. Is any persons’ life more important than that of an animal? Would you be willing to speak up for them? Are you up for the challenge? You might not be, but we shall see if I can change your mind after reading this. Humans have long used animals for a variety of purposes. For hundreds of thousands of years, people have hunted for food and clothing. Between 10,000 and 18,000 years ago, humans began to domesticate animals such as dogs, goats, sheep, and chickens as beasts of burden and as food. For at least 2,500 years, animals have been used in circuses and other forms of entertainment. In the second century C.E., the Greek scientist Galen conducted some of the first medical experiments on living animals. When one thinks of animal rights, I am sure they think of the sad commercials, or peta. Well there is more to it than that. There are tens of thousands of animal rights activists and organizations around the world, though relatively few are major players. Why is this? Why is it that we as a nation, heck even as a community will stand up for everything and anything except animals? They have feelings too, even if they can not show them like humans can, they still have them. They love...

...Animal Testing Introduction The application of animals to test a large number of products from household compounds and cosmetics to Pharmaceutical products has been considered to be a normal strategy for many years. Laboratory animals are generally used in three primary fields: biomedical research, product security evaluation and education. (Animal Experiments) It has been estimated that approximately, 20 million animals are being used for testing and are killed annually; about 15 million of them are used to test for medication and five million for other products. Reports have been generated to indicate that about 10 percent of these animals are not being administered with painkillers. The supporters of animal rights are pressurizing government agencies to inflict severe regulations on animal research. However, such emerging criticisms of painful experimentation on animals are coupled with an increasing concern over the cost it would have on the limitation of scientific progress. (Of Cures and Creatures Great and Small) Around the world, animals are utilized to test products ranging from shampoo to new cancer drugs. Each and every medication used by humans is first tested on the animals. Animals were also applied to develop anesthetics to ease human ailments and suffering during surgery. (Animal Experiments) Currently, questions have been raised about the ethics surround animal testing. As a result several regulations have been put in place to evaluate and control the...

...Section 1 Medicine and treatment Chapter 3: Extension study: Medicine and public health from Roman Britain to c1350 3.1 The Romans and approaches to medicine Exam practice question 1 (page 17) The Romans believed that disease was caused by an imbalance in the Four Humours. They believed that the body was made up of black bile, yellow bile, blood and phlegm, and that too much or not enough of one of these would cause illness. A fever, for example, showed that you had too much blood. This belief was developed by Galen from the work of Hippocrates, an Ancient Greek doctor. The Romans also believed that bad air could cause disease. They thought it was important to build cities and settlements away from swamps and marshes. This would have helped them avoid diseases like malarias which were caused by mosquitoes, but they didn’t understand why. The Romans also believed that dirt and sedentary lifestyles caused disease, because they encouraged the population to bathe regularly and exercise in the bath house. However, they would not have understood why this kept people healthy. Exam practice question 2 (page 18) In some ways the influence of Hippocrates on Roman medicine was extremely important. Hippocrates’s teachings included the theory of the four humours, which taught that the body was made up of four elements and too much of one of these would cause illness. He also taught the importance of clinical observation: watching a patient very carefully and keeping detailed...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
