Content: There are three parts to the small intestine. The duodenum is the first 25 cm (10 inches). The common bile duct enters the duodenum at the ampulla of Vater (hepatopancreatic ampulla). The jejunum is about 2.4 meters long (8 feet). Some digestion and absorption takes place in the first part of the jejunum. The ileum is about 3.6 meters long (12 feet). It extends from the jejunum to the ileocecal valve, which prevents the reflux of contents from the cecum back into the ileum. The lining of the ileum contains numerous patches of lymphoid tissue called Peyer’s patches, which diminish the bacterial content of the digestive system. Functions of the small intestine: secrete digestive enzymes (peptidases, sucrase, maltase, and lactase)
secrete buffers
absorb nutrients
