Answer:
To regulate water balance in the body
Explanation:
The kidneys are two bean shaped renal organs which perform a host of functions for the body such as regulating fluid balance, filtering minerals from the blood etc. Among their functions is the regulation of water balance in the body through the antidiuretic hormone.
When an athlete completes a physical activity and sweats a lot, the kidney reacts to the loss of water by sweat by adjusting urine output causing the body to produce lower and more concentrated urine.
The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body. Have a good day!!! Pls mark brainliest if helps!! :)
