Which of the following statements is incorrect?
a. ADH—prevents conversion of Angiotensinogen in blood to angiotensin
b. Aldosterone—facilitates water reabsorption
c. ANF—enhances sodium reabsorption
d. Renin—causes vasodilation
The answer is an option (a) ADH—prevents the conversion of Angiotensinogen in blood to angiotensin.
The posterior pituitary secretes vasopressin, also known as ADH (Antidiuretic Hormone). It prevents diuresis by aiding in the reabsorption of water from later tubule segments. By increasing the collecting duct's permeability for both salt and water and by speeding up ion and water transfer as indicated by the osmotic gradient, it controls the excretion of water.
