ADH stimulates the reabsorption of water in which of the following organs?
A
Liver
B
Kidneys
C
Pancreas
D
Lungs
Verified step by step guidance1
Step 1: Understand the role of ADH (Antidiuretic Hormone). ADH is a hormone produced by the hypothalamus and stored in the posterior pituitary gland. Its primary function is to regulate water balance in the body by stimulating water reabsorption in specific organs.
Step 2: Identify the organ responsible for water reabsorption. The kidneys are the primary organs involved in filtering blood, removing waste, and regulating water balance. ADH acts on the kidneys to increase water reabsorption in the nephron's collecting ducts.
Step 3: Eliminate incorrect options. The liver is involved in metabolism and detoxification, not water reabsorption. The pancreas is responsible for producing digestive enzymes and hormones like insulin, and the lungs are involved in gas exchange, not water regulation.
Step 4: Focus on the kidneys. ADH binds to receptors in the collecting ducts of the kidneys, increasing the permeability of the duct walls to water. This allows more water to be reabsorbed into the bloodstream, concentrating the urine.
Step 5: Confirm the correct answer. Based on the physiological role of ADH and the function of the kidneys, the correct answer is 'Kidneys.'
