What is egestion?

Egestion is the process of removing undigested and unabsorbed food materials from the body. It is the final step in the process of nutrition in animals.

After digestion and absorption, the remaining waste that cannot be utilized by the body passes into the large intestine. From there, it is stored temporarily and then eliminated from the body through the anus in the form of feces.

Egestion is important because it helps in maintaining internal cleanliness and prevents the accumulation of waste materials that could be harmful to the body.

It should not be confused with excretion, which involves the removal of metabolic wastes like carbon dioxide and urea.
