Renin increases blood pressure if necessary.

Question

Quizplus · Accepted Answer

Renin is an enzyme secreted by the kidneys that helps regulate blood pressure. It does so by converting angiotensinogen (a protein made in the liver and released into the bloodstream) into angiotensin I (a peptide hormone), which then undergoes further processing to become angiotensin II (a potent vasoconstrictor). This leads to an increase in blood pressure, as the narrowed blood vessels make it harder for blood to flow through them. Therefore, renin can increase blood pressure if necessary.
