Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ causes the collecting ducts to reabsorb more water.
A
ADH
B
renin
C
ANP
D
none of these is correct
Explanation: 

Detailed explanation-1: -Vasopressin increases the water permeability of the renal collecting duct cells, allowing more water to be reabsorbed from collecting duct urine to blood.

Detailed explanation-2: -Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine. A low level results in greater urine production.

Detailed explanation-3: -Explanation: ADH acts upon the collecting ducts and distal convoluted tubules of nephrons to increase water reabsorption. It causes an increase in the number of aquaporins in order to allow for this.
