Question

How does skin assist in the process of excretion?

• A. Through sweating.
• B. Through evaporation.
• C. By tanning.
• D. By wrinkling.

Answer 1

The correct option is A

Through sweating.

The skin excretes sweat through sweat glands throughout the body. The sweat, helped by salt, evaporates and helps to keep the body cool when it is warm. Skin assists in the process of excretion through sweating by eliminating water, salts and urea.
