Intestine Transplant. What Is the Small Intestine? The small intestine is made up of three segments, which form a passage from your stomach the opening between your stomach and small intestine is called the pylorus to your large intestine: Duodenum: This short section is the part of the small intestine that takes in semi-digested food from your stomach through the pylorus, and continues the digestion process.
The duodenum also uses bile from your gallbladder, liver, and pancreas to help digest food. Jejunum: The middle section of the small intestine carries food through rapidly, with wave-like muscle contractions, towards the ileum.
Ileum: This last section is the longest part of your small intestine. The small intestine is much smaller in diameter, but is much longer and more massive than the large intestine. Together the intestines take up most of the space within the abdominal body cavity and are folded many times over to pack their enormous length into such a small area. The intestines are located inferior to the stomach in the abdominal body cavity.
They are connected to the posterior wall of the abdomen by the mesentery, a thin vascular membrane. Blood vessels of the mesentery carry oxygenated blood to support the tissues of the intestines and carry nutrient-rich venous blood away from the intestines to feed the tissues of the body.
The small intestine is about 1 inch in diameter and about 10 feet long in a living body. It extends from the stomach to the large intestine and consists of 3 major regions: the duodenum, jejunum, and ileum. The large intestine is about 2. It receives fecal matter from the small intestine through the ileocecal sphincter. The smooth walls of the large intestine absorb water from fecal matter.
