Question

What is renin? Write it’s any two functions.
​

Answer 1

Answer:

Renin

Aspartic Protease Protein

Renin, also known as an angiotensinogenase, is an aspartic protease protein and enzyme secreted by the kidneys that participates in the body's renin–angiotensin–aldosterone system—also known as the renin–angiotensin–aldosterone axis—that mediates the volume of extracellular fluid and arterial vasoconstriction. Thus, it regulates the body's mean arterial blood pressure.

Answer 2

Answer:

Renin's primary function is therefore to eventually cause an increase in blood pressure, leading to restoration of perfusion pressure in the kidneys. Renin is secreted from juxtaglomerular kidney cells, which sense changes in renal perfusion pressure, via stretch receptors in the vascular walls.
