What is the main function of the small intestine?(use terms : villi, surface area,blood capillaries,why must large molecules be
alexdok [17]

Answer:

Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.

Explanation:  

The whole digestive tube is approximately eleven meters long, from the mouth to the anus.

The small or thin intestine is the longest organ of the digestive tube. It can reach up to 7 meters long, up to 3 centimeters in diameter, and it characterizes by being folded. These folds are called<u> villi</u><u>,</u> they project into the intestine light, and they are more concentrated in the first portion of the intestine, the duodene, decreasing to the final region of the organ.

Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.

The small intestine receives food from the stomach, and through peristaltic movements, it mixes and carries the material to different regions in the organ. The complex polymeric molecules are digested and transformed into simpler substances. The duodene receives secretions from intestinal glands such as bile and pancreatic juices and mixes them with digestive juices of its production. All of these secretions carry huge amounts of enzymes that will degrade food and transform it into soluble substances, such as amino acids. The intestine walls are covered by villi that <u>increase the absorption surface area.</u> Nutrients are absorbed by primary cells and transported to the bloodstream. Calciform cells secrete mucus to protect the epithelium during digestion. Villi also transport water from the blood to the intestinal tract, which helps in food decomposition. Enteroendocrine cells secrete hormones to the blood vessels and capillaries that enter each villus. When nutrients are small enough they go to enter the bloodstream.

Peyer's patches are nodules or cumulus of lymphatic tissue and other accessory cells, located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine, in the jejunum region. These patches represent the mucosa´s immunity system. In the jejunum, these follicles are isolated from each other in the intestine and low concentrated. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque.

A type of tumor in the pancreas called a glucagonoma produces and releases excess glucagon into the blood. How would this affect
Aloiza [94]

Answer:

The excess production of glucagonoma release glucagon in the blood causing increase level of glucose in the blood which in turn causes type 1 diabetes mellitus.

Explanation:

The islet of Langerhans cells in pancreas contain alpha cell that are mainly responsible for increase glucose level in the blood by secreting glucagon hormone which prevents the fall of glucose level in the blood.The glucagon is stored in the liver and is released by the process of glycogenolysis.

Type 1 diabetes mellitus is a disease when the body fails to produce insulin hormone that is released by the beta cells of islet of Langerhans in pancreas,which acts to reduce the level of glucose in the blood and thus maintain an equilibrium of glucose in the body.
