Vedclass · Answer

(A) When blood pressure increases,the walls of the atria of the heart are stretched. This stretching stimulates the cardiac wall to secrete a peptide hormone called Atrial Natriuretic Factor $(ANF)$. $ANF$ acts as a vasodilator (dilates blood vessels) and promotes the excretion of sodium and water,thereby reducing blood pressure. Conversely,$ADH$ (Antidiuretic Hormone) is released when blood pressure is low or blood osmolarity is high to conserve water and increase blood pressure. Therefore,an increase in blood pressure specifically triggers the release of $ANF$.

An increase in blood pressure causes the release of:
