Question

How does the skin help in controlling water balance and excretion?

Answer 1

Skin:

1. Skin, the outermost layer of the human body serves as the body’s initial barrier against foreign particles. It is the largest organ of the human body and functions as a barrier between outside and inside environment.
2. Skin helps in maintaining water balance in the body by preventing excess water loss through skin by evaporation.
3. The skin plays a role in excretion through the production of sweat by sweat glands.
4. Sweating eliminates excess water, salts and a small amount of urea.
