Duodenum, Jejunum, Ileum

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

The small intestine divides into the duodenum, where chyme meets pancreatic and bile secretions and most chemical digestion occurs; the jejunum, absorbing most nutrients; and the ileum, absorbing bile salts and vitamins.

Show

The duodenum neutralizes acidic chyme with pancreatic bicarbonate before digestion continues.

Watch for

The vermiform appendix sits at the ileum's junction with the large intestine but plays no significant digestive role itself.
