Solution

It is egestion not excretion. These two are different processes. Following are the difference between excretion and egestion:

Egestion Excretion

Discharge of undigested, leftover food from the gut. Discharge of metabolic wastes.

It takes place through anus and sometimes through mouth. It takes place through urethra, skin or mouth.

It is a part of digestion. It is a total separate life process.

The matter that is egested is faeces. The materials that are excreted are sweat, urine or carbon dioxide.
