GENERAL HISTOLOGY

Detailed explanation-1: -ADH makes the collecting ducts more permeable to water so that more water is reabsorbed. As a result, a small volume of concentrated urine is produced.

Detailed explanation-2: -Explanation: ADH is a hormone that increases permeability to water in the collecting ducts and therefore increases water reabsorption from the urine. This decreases the volume of water in the urine.

Detailed explanation-3: -ADH primarily affects the ability of the kidney to reabsorb water; when present, ADH induces expression of water transport proteins in the late distal tubule and collecting duct to increase water reabsorption.

Detailed explanation-4: -Answer and Explanation: The true statement about the role of antidiuretic hormone (ADH) in regulating kidney function is C. ADH promotes the insertion of water channels into the collecting duct. The action of ADH is dependent on reabsorption of water into the system so that balance of water can be maintained.

Detailed explanation-5: -What happens if I have too little anti-diuretic hormone? Low levels of anti-diuretic hormone will cause the kidneys to excrete too much water. Urine volume will increase leading to dehydration and a fall in blood pressure.
