Which part of the nephron is affected by aldosterone?

Renin is secreted from

The $JGA$ (Juxta Glomerular Apparatus) is a special sensitive region formed by cellular modifications in . . . . . . related to the same nephron.

An increase in blood pressure causes the release of:

Arrange the following events occurring in the 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 the 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 $II$.

$JG$ cells of the kidney secrete:
