Why is egestion not a part of excretion?
Asked by | 16th Jun, 2008, 07:11: PM
Egestion is the elimination of undigested material in solid or semi-solid form from the digestive tract through the anus. Excretion on the other hand is getting rid of metabolic wastes formed from the chemical reactions of the body, such as in urine, sweat, etc. Also remember that the wastes of excretion are liquids and gases whereas during egestion, solid wastes are removed. Hence egestion and excretion are 2 different aspects.
