Water output is largely controlled by varying

A.

cutaneous transpiration

B.

drinking

C.

urine volume

D.

sweating

Answer and Explanation

The Correct Answer is C

A. Cutaneous transpiration: While cutaneous transpiration (evaporation of sweat from the skin) contributes to water loss, it is not the primary mechanism controlling water output.

 

B. Drinking: Drinking affects water intake rather than output. It does not directly control how much water is excreted from the body.

 

C. Urine volume: Urine volume is the primary means by which the body regulates water output. The kidneys adjust urine volume to maintain fluid balance and homeostasis.

 

D. Sweating: Sweating contributes to water loss but is not the primary mechanism for controlling overall water output compared to urine production.
