Talk about digestion and absorption in the small intestine.
chyme moves into the small intestine by way of the pyloric sphincter. Digestion and absorption happen in the small intestine. The 3 sections of the small intestine are the duodenum, jejunum, and the ileum.The small intestine produces lipase (lipid digestion), aminopeptidases (for polypeptide digestion), and disaccharidases (for digestion of maltose, lactose, and sucrose). The small intestine also secretes secretin which stimulates the release of sodium bicarbonate from the pancreas. The small intestine is lined with villi (capillaries and lacteals) which increase the surface area for absorption of nutrients into the blood.
