Detailed explanation-1: -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-2: -Vasopressin (antidiuretic hormone) acting at V2 receptors enhances water reabsorption by increasing aquaporin-2 channels in the renal collecting duct.
Detailed explanation-3: -Anti-diuretic hormone acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney.
Detailed explanation-4: -It is mainly involved in regulating and balancing the amount of water in the blood and increasing the glomerular blood flow by increasing the blood pressure. Higher the concentrations of ADH tightens the blood vessels, which increases the blood pressure.
Detailed explanation-5: -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.
