Detailed explanation-1: -Defecation Eliminates Waste From the Body The body expels waste products from digestion through the rectum and anus. This process, called defecation, involves contraction of rectal muscles, relaxation of the internal anal sphincter, and an initial contraction of the skeletal muscle of the external anal sphincter.
Detailed explanation-2: -Elimination. The food molecules that cannot be digested or absorbed need to be eliminated from the body. The removal of indigestible wastes through the anus, in the form of feces, is defecation or elimination.
Detailed explanation-3: -The large intestine eliminates solid wastes that remain after the digestion of food. The liver breaks down excess a mino acid s and toxins in the blood.
