An increase in the production of ADH affects the kidney tubules by
A)inhibiting reabsorption of sodium ion in the collecting duct.
B)decreasing the permeability of the glomerulus to water.
C)causing the walls of the collecting duct to become more permeable to water.
D)inhibiting the reabsorption of water in the glomerulus.
E)decreasing the insertion of aquaporins into the membranes of cells that line the collecting ducts.

Question

Quizplus · Accepted Answer

ADH (antidiuretic hormone) acts on the collecting ducts of the kidneys to increase their permeability to water, which can then be reabsorbed back into the body. This is done through the insertion of aquaporin channels into the membranes of the cells that line the collecting ducts. As a result, more water is reabsorbed back into the bloodstream, leading to a decrease in urine output and an increase in body water retention.
