that function together to transform food substances to energy and nutrients that are needed in the body. The digestive system is made up of the alimentary canal which include the mouth or oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines including the accessory organs of digestion which involve the teeth, tongue, salivary glands, liver, gall bladder and the pancreas. The alimentary canal and the accessory organs perform the following functions which include;…

Homeostasis Assignment Jeanette Galvez ZOOL 2021.03 Instructor: Elizabeth Samuel Oct. 14 2015 The human digestive system involves the process of food throughout the body. The human body must break down the food to its basic form so that it may be properly absorbed and used. The human digestive system is essentially one big tube that starts from the mouth and moves its way down to the anus (Farabee 1992). The entire starts from the mouth where salivary glands along with teeth, starts to…

It was April 4th, and as I looked into the blinding lights over my head, I anxiously waited for the anesthetics to take hold of me. The sooner I’m knocked out, the sooner I’ll wake up, and the sooner I can get out of here. I blinked and realized that the masked men above me had begun to spin in and out of eyesight, so I allowed the drugs to sweep me away as I tried to hold on to the vision of friends, and track meets, and the sweet sixteen soon to come. I vaguely wondered if my sisters had…

Lucy also consume carbohydrates such as berries and oranges, (the process in which the food moves down from the mouth to the rectum is the same as above.) it is first digested mechanically by chewing. The digestion of carbohydrates begins in the mouth by salivary enzyme, amylase, the fruits starches are digested into maltose and disaccharide. As the food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place as the HCl in the stomach stops amylase…

epiglottis. This is what sends food to the esophagus and this is what doesn’t let the food go down to the trachea and into the lungs. The process of food moving down to the esophagus is called peristalsis. Peristalsis uses a coat of muscles in the intestines and esophagus. These muscles then therefore calm down and relax and become into a wave motion to let the food pass straight forward. The next…

you her final story. October 26th 2016, was the day my grandma was diagnosed with bile duct cancer. Bile duct cancer, also called cholangiocarcinoma, is a cancer in the tubes that brings the digestive fluid bile though the liver to the small intestine. About 8,000 people in the United States are diagnosed with bile duct cancer each year. This type of cancer is also a terminal cancer or a cancer that cannot be treated. On October 26th, I got a call from my mom saying, “Your grandma is in the…

With treatment, many people with Crohn 's disease are able to function well. In some people with Crohn 's disease, only the last segment of the small intestine (ileum) is affected. In others, the disease is confined to the colon (part of the large intestine). The most common areas affected by Crohn 's disease are the last part of the small intestine and the colon. Signs and symptoms of Crohn 's disease can range from mild to severe. They usually develop gradually, but sometimes will come on…

The Importance of the Liver and the effects of Cirrhosis The liver is known to be the largest organ in the body weighing at about three pounds in adults. It is located in the right upper quadrant area, more specifically in the hypochondriac region beneath the diagram. The liver is one of the most important organs as it performs many metabolic roles. Without it, we would not have the ability to survive. The liver is responsible for performing important functions such as making proteins that aid…

Lipid Digestion: Absorption and Transport of Lipids Lipid digestion occurs primarily in the small intestine though a small amount of lipids are broken down in the stomach. Special enzymes called lipases breakdown triglycerides the most abundant lipids in the diet and phospholipids. Lingual lipase secreted by glands in the tongue and gastric lipase secreted by gastric chief cells hydrolyze a small amount of triglycerides into fatty acids and monoglycerides. As chyme enters the duodenum from the…

acid reflux into the esophagus is reduced and associated symptoms are alleviated over time. While effective, a number of side effects have been associated with proton pump inhibitor use. Proton pump inhibitors are initially absorbed via the small intestine and then distributed to gastric parietal cells. They are activated in the acidic environment of the parietal cell’s vesicles and secretory canaliculi (Suzuki). Proton pump inhibitors require profound acidity (a pH level less than 1 is ideal)…
