How many of the following statements are true about ADH?
a. Profuse sweating suppresses ADH.
b. ADH prevents diuresis.
c. Excess drinking of water activates ADH.
d. ADH is a vasoconstrictor.
Profuse sweating stimulates the release of ADH (Excess loss of body fluids activates the osmoreceptors).
ADH prevents diuresis (loss of excess water in urine is called diuresis).
Excess drinking of water suppresses ADH (Increase in body fluid volume can switch off the osmoreceptors).
ADH is a vasoconstrictor (ADH can affect the kidney function by its constrictory effects on blood vessels). Hence called vasopressin.
