Digestion ends in small intestine. Waste products are excreted from our body through large intestine. Excess water and salts are absorbed from intestine through muscular finger like projections called Villi.

Many microbes present in alimentary canal of some animals like cones help in digestion and absorption of food. Bacteria in our large intestine helps in bowel movement.

Undigested waste is collected in large intestine and stored in rectum. It is excreted through anus. Sphincter muscle regulated the excretion of waste products from our body.

Residue of digested food passes into large intestine. Large intestine has three regions i.e C shaped colon, cecum and thick tubular rectum.

Auerbach 's  plexus is part of autonomic nervous system  in vertebrates lying between the two main muscular layers  of intestine and controlling its peristaltic movements .

In the wall of caecum and colon, the longitudinal muscle layer is thickened along three lines, forming the taeniae.
