This last lecture on the digestive system examines the physiology of the small and large intestines and the rectum. First, we examine mechanical and chemical digestion in the small intestine. We turn next to the large intestine or colon, examining the reflexes that move feces into and through the colon for excretion. Finally, we examine the physiology of defecation.
