Which of the following statements regarding the hormonal regulation of kidney function is incorrect?

Options

  1. AA fall in glomerular blood flow or GFR activates the JG cells to release renin into the blood.
  2. BAngiotensin II is a powerful vasoconstrictor that increases the glomerular blood pressure and thereby GFR.
  3. CAn increase in blood flow to the atria of the heart causes the release of Atrial Natriuretic Factor (ANF), whi
  4. DExcessive loss of fluid from the body stimulates the hypothalamus to release antidiuretic hormone (ADH) from t

Correct answer

C. An increase in blood flow to the atria of the heart causes the release of Atrial Natriuretic Factor (ANF), whi

Step-by-step solution

An increase in blood flow to the atria of the heart causes the release of Atrial Natriuretic Factor (ANF). ANF causes vasodilation (dilation of blood vessels) and thereby decreases the blood pressure. It acts as a check on the renin-angiotensin mechanism. The statement in option (C) is incorrect because it claims that ANF leads to vasoconstriction, whereas it actually causes vasodilation. The other statements correctly describe the roles of JG cells, Angiotensin II, and ADH in the hormonal regulation of kidney func
