Basicfunctions of stomach
Reservoir for up to 3 hours
Chemical digestion of proteins

Basicfunctions of stomach

Chemical digestion of proteins
Slow release of chyme into small intestine
Functions of small intestine
Absorption of undigested food
Digestion
3 Main juices released in small intestine
Intestinal juice(neutralizes accidic chyme) Pancreatic juice (exept for bile juices have enzymes that help with digestion) Bile(helps with fat absorption)
Accessory organs
