The functioning of the kidneys is efficiently monitored and regulated by hormonal feedback mechanisms involving the hypothalamus, JGA and to a certain extent, the heart. From given statements about JGA control, select correct option from below:

(i) It is controlled by Renin-Anigotensin mechanism.

(ii) A fall in glomerular blood flow/glomerular blood pressure/GFR can activate the JG cells to release rennin.

(iii) Renin converts angiotensinogen to angiotensin I.

(iv) Angiotensin II, being a powerful vasoconstrictor, increases the glomerular blood pressure and thereby GFR.

(v) Angiotensin I activates the adrenal cortex to release aldosterone.

(vi) Aldosterone causes reabsorption of N + and water from the distal parts of the tubule this also leads to an increase in blood pressure and GFR.
