Question

Which of the following is not a source of water loss for the body?
A) catabolism of food
B) the lungs
C) the kidneys
D) the skin

Accepted Answer

Catabolism of food actually generates water, so it does not result in water loss for the body. The other options (lungs, kidneys, and skin) are all sources of water loss through respiration, urination, and perspiration, respectively.
