Question

Fluid intake is regulated by the ________.
A) kidneys
B) pituitary
C) hypothalamus
D) nephrons

Accepted Answer

The hypothalamus is responsible for regulating fluid intake through thirst. It detects changes in the concentration of blood and signals the body to either increase or decrease fluid intake accordingly. The kidneys are responsible for regulating fluid balance in the body, while the pituitary gland plays a role in regulating hormones but not specifically fluid intake. The nephrons are the functional units of the kidneys and help with fluid filtration and excretion.
