Stomach - Large bowel Template:Toc

Anatomy[edit | edit source]

The small bowel or small intestine connects the stomach to the large intestine. The parts of the small intestine are the duodenum, jejunum, and ileum.

Function[edit | edit source]

The small intestine absorbs most of the nutrients from the chyme. The pyloric sphincter lets only a tiny bit of chyme go into the small intestine at a time. The small finger-like projections are called villi. Villi help in the absorption. The jejunum absorbs sugars, amino acids, and fatty acids. The ileum absorbs bile acids, fluid, and vitamin B12.
