Which one of the following statements is correct with respect to kidney function regulation?

  1. A
    During summer when body loses lot of water, the release of ADH is suppressed
  2. B
    When someone drinks lot of water, ADH release is suppressed
  3. C
    Exposure to cold temperature stimulates ADH release
  4. D
    An increase in glomerular blood flow stimulates formation of Angiotensin II

Solution & Step-by-step Explanation

ADH (Antidiuretic Hormone) promotes water reabsorption. When a person is well-hydrated or drinks excess water, the blood becomes dilute (low osmolarity), which suppresses the release of ADH from the posterior pituitary, leading to more dilute urine.
