Answer:

removal of any waste materials from our body is excretion.

Answer 2

Answer:

Solution:

False

• Removal of solid undigested food is egestion.
• Removal of waste substances from the body.

Excretion is the removal of waste products of metabolism (means that the waste product has been made by the body itself) from the body. If allowed to accumulate, these would prevent the maintenance of a steady state. Egestion or defecation is the removal of undigested food from the gut and is not regarded as excretion because the material taken into the gut through the mouth is not made by the body itself.
