Hydrochloric acid makes an acidic environment in the stomach that promotes promotes polysaccharide digestion. Lipase, produced by the pancreas, digests the emulsified fats into fatty acids. Bile, synthesized by the liver and stored in the gall bladder, digests fats which will then be absorbed in the small intestine The acidic environment converts the inactive pepsin into its active form: pepsinogen. Pepsinogen digests proteins in the stomach.arrow_forward

In the resting state the internal sphincter is relaxed while the external sphincter is contracted. Both sphincters must be relaxed in order for feces to pass out of the body. As the rectum fills it stimulates the internal sphincter to relax and the external sphincter to contract.arrow_forward
