The endocrine part secretes insulin when the blood sugar becomes high; insulin moves glucose from the blood into the muscles and other tissues for use as energy. The endocrine part releases glucagon when the blood sugar is low; glucagon allows stored sugar to be broken down into glucose by the liver in order to re-balance the sugar levels.
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine , and receives bile and pancreatic juice through the pancreatic duct to aid in digestion .
Bowel twist (or similarly, bowel strangulation) is a comparatively rare event (usually developing sometime after major bowel surgery). It is, however, hard to diagnose correctly, and if left uncorrected can lead to bowel infarction and death. (The singer Maurice Gibb is understood to have died from this.)

The ileum, along with the jejunum, is suspended inside the mesentery, a peritoneal formation that carries the blood vessels supplying them (the superior mesenteric artery and vein), lymphatic vessels and nerve fibers. [3] There is no line of demarcation between the jejunum and the ileum. There are, however, subtle differences between the two: [3]
Underlying the epithelium is the lamina propria, which contains myofibroblasts, blood vessels, nerves, and several different immune cells, and the muscularis mucosa which is a layer of smooth muscle that aids in the action of continued peristalsis and catastalsis along the gut.
Getting your body moving can help your bowels do the same. “Regular physical activity, even simply walking, can help to stimulate your bowels to make your stools more regular,” says Moore.
Others have a spiral direction. The latter usually extend a little more than once around the bowel, but occasionally two or three times. While the larger folds are about 1 cm in depth at their broadest part, most folds are smaller. There tends to be an alternating pattern between larger and smaller folds. [1]
The ileocecal valve is typically located on the last fold before entry into the cecum and can be located from the direction of curvature of the appendiceal orifice, in what is known as the bow and arrow sign. [4] Intubation of the ileocecal valve is typically performed in colonoscopy to evaluate the distal, or lowest, part of the ileum.
