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
chief cells

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.
