Arrange the following events occurring in Renin-Angiotensin mechanism in the correct order:
(A) Increase in blood pressure and glomerular filtration rate.
(B) Reabsorption of Na+ and water from distal parts of tubule due to aldosterone.
(C) Fall in glomerular filtration rate.
(D) Vasoconstriction by Angiotensin II and release of aldosterone.
(E) Renin converts angiotensinogen into Angiotensin I, followed by Angiotensin II.
A fall in GFR triggers renin release, producing angiotensin II, which causes vasoconstriction and aldosterone secretion. Aldosterone increases Na+ and water reabsorption, restoring blood pressure and GFR.
The JGA (Juxta Glomerular Apparatus) is a special sensitive region formed by cellular modifications in ______ related to the same nephron.
The juxtaglomerular apparatus (JGA) is formed by the distal convoluted tubule and the afferent arteriole and helps regulate glomerular filtration rate through the renin-angiotensin mechanism.
