So I have a few questions about it: What is AP humanities? (The teacher has a bunch of art around his room so I'm assuming it has to do with art) What do you do in AP humanities? Is... show more We just got our class choices for next year and as I was looking over the AP choices, I noticed that AP humanities was on it.
Angiotensin-converting enzyme. Angiotensin-converting enzyme (EC 3.4.15.1), or ACE, is a central component of the renin-angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. It converts the hormone angiotensin I to the active vasoconstrictor angiotensin II.
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. The juxtaglomerular cells are also stimulated to release renin by signaling from the macula densa.
