Small intestine

Small intestine
The small intestine is the portion of the digestive system most responsible for absorption of nutrients from food into the bloodstream. The pyloric sphincter governs the passage of partly digested food from the stomach into the duodenum. This short first portion of the small intestine is followed by the jejunum and the ileum. The ileocecal valve of the ileum passes digested material into the large intestine.
