Pancreas Case Study

The oral cavity is the first part of the digestive system, it is basically the mouth containing the teeth, the tongue, salivary glands, uvula, and the pharynx. When food enters the mouth it is welcomed by the teeth which immediately start the mechanical digestion that occurs in the mouth. The teeth work along with the tongue to turn the food into bolus (small rounded masses of chewed food). While the food is being chewed and moved around the salivary glands secrete saliva, which has the purpose of helping break down the food into simpler molecules and make it easier to be swallowed. While doing the action of swallowing, the uvula and the rest of the soft palate move to close off the nasopharynx, to stop food from entering the nasal cavity.

It is a very important part of the digestive system and it is a critical controller of blood sugar levels. It is located between the stomach and the spine, and it is both an exocrine and endocrine gland. The pancreas has an endocrine function because it releases juices directly into the bloodstream, and it has an exocrine function because it releases juices into ducts. The path in which the pancreas delivers the juices, meaning directly or into ducts, is the main difference of an endocrine and exocrine function. The pancreas produces some important hormones, enzymes: proteases, lipase, amylase, ribonuclease, deoxyribonuclease, gelatinase, and elastase, and secretes pancreatic juices, which contain digestive enzymes that pass through the small intestine. Exocrine cells within the pancreas produce enzymes, as mentioned above, that help during the process of digestion. The hormone proteases breaks down peptide bonds in protein foods, while elastase breaks down proteins. Gelatinase allows the body to hydrolyse gelatin into its correspondent sub- compounds. Lipase helps the body absorb fats, while amylase helps with the conversion of starch into sugars. Ribonuclease degrades RNA into smaller pieces, while deoxyribonuclease hydrolyzes DNA into nucleotides. So, when food enters the stomach, the exocrine cells release pancreatic enzymes into ducts that eventually lead to the main pancreatic duct. This duct

It wraps around the border of the abdominal body cavity from the right side of the body. It looks sort of like a snake and its color may vary dependingon what the person has eaten recently.

Small Intestine: The small intestine is about 10 to 20 feet in length. It wind throughout the abdominal body cavity inferior to the stomach. It looks like a snake and it may varies in color depending on what the person ate. It is called the small intestine due to the diameter size because it is longer in length than the large intestine.

Function

The large intestine is the final section of the gastroinestial tract that performs the vital task absorbing water and the vitamins while converting diggested food into feces although its shorter than the small intestine in length the large intestine is considerbly thicker in diameter. It absorbs essential vitamins produced by gut bacteria and reclaiming water from feces.

The Small intesine: Most absorbtion of the nutients occur in the small intestine. it happens in the small bladder it carries it in continuation with the stomach up to the colon from where the large intestine carries it to the rectum and out of the
