Answer:
The correct answer is "regulate body fluid by controlling excretion from sweat glands".
Explanation:
Regulate body fluid by controlling excretion from sweat glands is not a function of the kidneys. The kidneys regulate body fluid by controlling the level of water that it is excreted in the urine. The brain and the sweat glands themselves are the two organs that control the level of body fluids from sweat glands, and by doing this they allow body fluid homeostasis.
