04/03/17 Ch. 15: Digestion and Nutrition
Objective: Students will be able to describe the major organs of the digestive system and their functions.
Alimentary Canal• Draw the alimentary canal:• Label the major tissue types that make up each organ and the major functions that occur at each organ. • How do the tissue types facilitate their function?

Stomach
Stomach contains:• mucous (epithelial) cells (goblet cells)
release alkaline coating to protect stomach from HCl• chief cells
secrete digestive enzymes• Pepsin: in gastric juice• breaks down proteins into polypeptides• requires HCl to form from pepsinogen• parietal cells
secrete HCl

Small Intestine
Enzymes in Small Intestine• Peptidases: in villi and microvilli• breaks down polypeptides into amino acids• Sucrase, maltase, lactase• breaks down disaccharides into monosaccharides• Intestinal lipase• breaks down fats into fatty acids and glycerol
Small Intestine contains:• mucous cells (goblet cells)• release alkaline coating to protect from HCl from stomach• also releases watery fluid w/out digestive enzymes that help when pancreatic and liver enzymes enter.

• as chyme enters the small intestine, the small intestinal wall distends. This triggers the nerves to signal the cells to release intestinal secretions

Large Intestine
Large Intestine contains:• mucous cells (goblet cells)• secrete mucous--does not contain enzymes for digestion
primary function • reabsorption of water
