The overall effect of renin release will be to
A) lower blood pressure.
B) lower blood volume.
C) convert angiotensin II into angiotensin I.
D) inhibit aldosterone secretion.
E) increase blood pressure.
Renin
An enzyme secreted by the kidneys that plays a key role in regulating blood pressure by converting angiotensinogen to angiotensin.
Angiotensin II
A potent vasoconstrictive peptide that plays a critical role in blood pressure regulation and fluid balance.
Blood Pressure
The force exerted by circulating blood upon the walls of blood vessels, often measured to assess heart and blood vessel health.

Final Answer :
E
Explanation :
Renin release is part of the renin-angiotensin-aldosterone system (RAAS), which ultimately leads to an increase in blood pressure. Renin converts angiotensinogen into angiotensin I, which is then converted to angiotensin II, a potent vasoconstrictor. Angiotensin II also stimulates the secretion of aldosterone, which promotes sodium and water retention, increasing blood volume, and further raising blood pressure.
