...Digestive System Mouth The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested. Esophagus Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow. Stomach Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow. Small intestine made up of three segments — the duodenum, jejunum, and ileum — the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver. Pancreas The pancreas secretes digestive enzymes into the duodenum, the first segment of the small intestine. These enzymes break down protein, fats, and carbohydrates. Liver The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine. Gallbladder The gallbladder stores and concentrates bile, and then releases it into the duodenum to help absorb and digest fats. Colon (large intestine) The colon is a 6-foot long muscular tube that connects the small intestine to the rectum. The large intestine is made up of the cecum, the ascending (right) colon, the transverse (across) colon, the descending (left) colon, and the sigmoid colon, which connects to the rectum. The appendix is a small tube attached to...

...Respiratory system Nose | Air enters and leaves the respiratory system through the nose. It warms and moistens the air before it reaches the lungs, and helps remove unwanted particles, like dust and soot. | Trachea | The trachea is also known as the windpipe. It is a bony tube, which connects the nose and mouth to the lungs, hence is an important part of the respiratory system in vertebrates | Lungs | The lungs take in oxygen, which the body's cells need to live and carry out their normal functions. The lungs also get rid of carbon dioxide, a waste product of the cells. | Nervous system Brain | The brain is like a central computer that control bodily functions. It is protected by the skull to reduce damage. It is divided into many parts, including the cerebrum and brain stem. It stores and sorts out information before sending out any necessary commands. It is the centre of control and its job would be incomplete without the spinal cord. | Nerves | Each nerve is connected to a particular area and is responsible for connection to and from different regions of the body. ‘Multiple sclerosis’ is a problem which can damage nerves and prevent signals to travel from them. | Spinal cord | The spinal cord is a long bundle of nerve tissues. It is protected by the vertebrae so it doesn’t get damaged. There is also fluid that helps protect nerve tissue, keeping it healthy by removing waste products. The brains job would not be possible without the spinal cord. | Sense...

...carry down) begins in the tail of the epididymis and ends by joining the duct of the seminal vesicle to form the ejaculatory duct. It is about 45 cm long and ascends in the spermatic cord. It passes through the inguinal canal and then crosses over the external iliac vessels to enter the pelvis minor. It passes along the lateral wall of the pelvis where it lies external but adherent to the parietal peritoneum and medial to the vessels and nerves. During its course no other structure intervenes between it and the peritoneum. The ductus deferens crosses the ureter near the posterolateral angle of the bladder. At first it lies superior to the seminal vesicle and then it descends medial to the ureter and this vesicle. The ductus deferens enlarges to form the ampulla of the ductus deferens as it passes posterior to the bladder. It then joins the duct of the seminal vesicle to form the ejaculatory duct. Arterial Supply and Venous Drainage of the Ductus Deferens The artery of the ductus deferens is closely applied to its surface. It is tiny and arises from the superior (or inferior) vesical artery. It terminates by anastomosing with the testicular artery, posterior to the testis. The veins accompany the arteries. Innervation of the Ductus Deferens Innervation is derived from the inferior hypogastric plexus. The ductus deferens is richly innervated by autonomic...

This occurs by closing off the bladder neck during climax by means of coordinated muscle contractions of the vas deferens, seminal vesicles, ejaculatory ducts, ischiocavernosus and bulbocavernosus muscles (emed). Benign Prostatic Hyperplasia (BPH) is an enlarged prostate. Proliferation of the cellular elements of the prostate lead to chronic bladder outlet obstruction. This causes urinary retention, renal insufficiency, recurrent urinary tract infections, and gross hematuria. The prostate doubles in size during puberty, and after age 25, the prostate continues to grow. The exact cause of BPH is not known but it...

...Diabetes and Urinary Incontinence The most common symptom of diabetics (type 1 & type 2) is frequent urination. Excess glucose builds up in the blood stream due to which the fluid gets pulled back from the tissues, resulting in increased thirst. The constant thirst makes you drink more water and you may have to urinate often. The excess glucose that the body produces is excreted out by urinating more than normal. Diabetics and nerve damage Diabetics may cause nerve damage and this includes bowel and bladder nerves too. The autonomic, cranial and peripheral nerves of the nervous system may be damaged if you are diabetic. The autonomic nerves pass from spinal cord to lungs, heart, stomach and bladder. When these nerves get damaged they can...

...Abstract Kidney stones are a very common and debilitating disorder that affects the urinary system. These stones are formed from substances that are naturally occurring in the body, but become problematic when they reach highly concentrated levels in the kidneys. Although the formation of kidney stones are not fully understood it is believed that certain foods can increase the risk for developing this urinary disorder. Changes in dietary lifestyles have been shown to help prevent the recurrence of kidney stones. During the acute phase of kidney stones, patients may experience certain symptoms such as painful urination, blood in their urine, or have sharp pains in their lower back, flank area, or lower abdomen. In order to diagnose kidney...

...They are often painful when passing through the urinary tract. They usually don't cause ever lasting damage to the inner body. This happens when the urine has more crystal friendly substances like calcium, oxalate and uric acid. Rather than the fluid in the urine can diluting. At the same time, the urine may be below average for substances that prevent crystals from sticking together forming a kidney stone.Now preventing them just has to do with having a healthy on point diet. Most importantly you should drink lots of water because the biggest risk factor is not taking in enough water. You should get an adequate amount of magnesium in your body. Not to much but not too little. AS well as avoiding sugary foods including fructose and sodas. Those are the main reasons people get Kidney Stones. Exercising will help avoid these stones. Staying fit and exercising is a great way to help also. Avoiding non fermented soy would help with all like all these other factors, but this is not...

...in Humans and Salmon Anthony Salgado BIO/101 January 22, 2015 Dr. Ellen Sparger Water Balance in Humans and Salmon Water balance is a very important function that most of us take for granted. Maintaining good hydration is essential for life, not just for humans, but also for animals like the salmon. Humans can go without food for more than thirty days, but cannot go without water for more than just a few days. This is the same for salmon, they can go without food longer than water. Salmon stop eating when they enter fresh water to spawn. Water balance is very important for their cycle of life. Humans and Salmon have similar organs (See picture of a salmon’s internal anatomy at end of paper) as both species have kidneys and bladders to help maintain their water balance. It is amazing to see how the body works in keeping us alive. Water is the key, and according to the Mayo clinic (2014) the water in our bodies make up about sixty percent of our body weight, this is why it is very important to stay hydrated. We lose almost a half-gallon of water per day just by living and doing our daily routines, this is why all of us should know how much water we should drink per day. Everyone has probable heard we should drink eight glasses of water per day. There is no hard evidence to support this but the Mayo Clinic (2014) reports this drinking eight glasses of water per day is not far off from their recommendations. They recommend men drink about thirteen cups of water...

...Kidney stones are hard lumps of crystals that form in the kidneys and cause severe pain. They are more common in the everyday working adults than they are in the elderly but can occur at any point in life. Kidney stones are typically more common in men but are increasing in women without a known cause. Nearly 75% of kidney stones are composed of calcium oxalate, and 10-12% are composed of uric acid. Stones can be smooth or rough. Not only are kidney stones incredibly painful, and can also lead to multiple problems, such as urinary tract infections or kidney infections. It is is critical to know the symptoms, treatments, and how to prevent them. The kidneys are bean-shaped organs on each side of our spine that maintain stable volume, electrolyte...
