Control of Tubular Re absorption and secretion
-Decrease in blood flow to the kidney:
Renin converts angiotensinogen into angiotensin I.
Another enzyme made by the lungs, angiotensin converting enzyme (ACE), converts angiotensin I to angiotensin II,
This increases thirst, increasing ADH secretion, increasing aldosterone secretion, and causing vasoconstriction. These increase blood pressure by increasing fluid volume.
