ADH

Question

ADH
A) is secreted by the anterior pituitary gland.
B) is a mineralocorticoid that is secreted by the adrenal cortex.
C) stimulates the collecting duct to reabsorb water.
D) increases the GFR.

Accepted Answer

ADH (antidiuretic hormone), also known as vasopressin, is secreted by the posterior pituitary gland. It acts on the collecting ducts of the kidneys, increasing their permeability to water and allowing more water to be reabsorbed back into the bloodstream. This leads to a concentration of urine and a decrease in urine output. ADH does not affect the glomerular filtration rate (GFR), which is regulated by other factors.
