Antidiuretic Hormone (ADH) _______

Question

Antidiuretic hormone (ADH) _______.
A) is an enzyme produced by the kidney
B) makes the collecting ducts more permeable to water
C) is produced when excess fluid is present in the body
D) activates the renin-angiotensin-aldosterone pathway

Accepted Answer

Antidiuretic hormone (ADH) makes the collecting ducts of the nephrons in the kidney more permeable to water, ultimately leading to reabsorption of water and a decrease in urine output. ADH is produced in the hypothalamus and released from the pituitary gland in response to changes in blood volume and concentration, specifically when water levels in the bloodstream are low.
