All right, renin is an enzyme that helps maintain and stabilize blood pressure.
00:10
And this question is asking, where is it made? and so in order to understand that, we need to look at something called the juxta -glomular apparatus.
00:22
And what the juxta -glomular apparatus is, is it is a part of a nephron called the macula densa, working with a group of cells in your blood vessel called the granular cells.
00:43
And so this part over here is a blood vessel, specifically a type of blood vessel called an arterial.
00:49
And this part over here is in your kidney, specifically in your nephron, and even more specifically in the distal convoluted tubules.
00:59
And so what these two groups of cells do is they communicate with each other, to tell when blood pressure has changed.
01:08
And so it will tell blood pressure has been changed and the kidney will change its function appropriately to then stabilize that blood pressure...
