Small intestine = Absorption of nutrients from digested food. Large intestine = Absorption of water. Anus = control the expulsion of wastes (stool).

Fuction of small and large intestines : The small intestine is where the vast majority of digestion takes place. Most food products are absorbed in the small intestine.The large intestine is responsible for absorption of water and excretion of solid waste material. Food and waste material are moved along the length of the intestine.Waste is solid because most of the water has been removed by the intestines. Function of Anus: Anus is a 2-inch long canal consists of the pelvic floor muscles and the two anal sphincters . The lining of the upper anus is specialized to detect rectal contents. The anus is surrounded by sphincter muscles that are important in allowing control of stool. The pelvic floor muscle creates an angle between the rectum and the anus that stops stool from coming out when it is not supposed to. The internal sphincter is always tight, except when stool enters the rectum.
