The main function of aldosterone in Renin-Angiotensin mechanism is:
| 1. | It converts angiotensinogen in blood to angiotensin I. |
| 2. | It is a powerful vasodilator. |
| 3. | It causes reabsorption of Na+ and water from the distal parts of the tubule. |
| 4. | It activate the JG cells to release rennin. |
