Intestine Ileum

The ileum is the part of the intestine located between the small intestine and the large intestine. It is about 1.5 meters long and plays an important role in digestion.

The ileum begins at the ileocecal valve, which separates the small and large intestines, and ends at the level of the sacrum. It consists of two parts: ascending and descending.

The ascending colon is about 60 cm long and is located in the abdominal cavity. It starts from the ileocecal valve and runs up to the stomach. On its way, it crosses several organs such as the liver, pancreas and spleen.

The descending colon, the ileum, is longer and is located in the pelvis. It continues from the ascending colon and descends to the colon. Here it also crosses many organs, including the bladder, rectum and anus.

The process of digestion occurs in the ileum. Food that enters it from the small intestine undergoes further digestion and absorption of nutrients. In the descending colon of the ileum, the processes of absorption of water and electrolytes, as well as the formation of feces, occur.

In addition, the ileum plays an important role in the body's immune system. It contains cells that protect the body from infections and other pathogenic factors.

Abnormalities in the ileum can lead to various diseases, such as intestinal obstruction, inflammatory bowel disease, irritable bowel syndrome and others.

The ileum is the final section of the small intestine in animals and humans. It got its name from the hole of the same name in the greater sciatic foramen. The lower third of the abdominal cavity is located to the right of the cecum. It has a length of 20 to 30 cm and a diameter to length ratio of 0.47 to 0.56 in men and from 0.52 to 0.69 in women. It begins with the intestinal opening and passes into the iliac groove, where it forms a rotary-superior bend. In the iliac region it reaches the place of confluence. In humans, the intestine has a mesenteric section.
