You are AMAZING!!!! I LOVE YOUR VIDEOS! They help so much with my physiology course, and you really do have a gift for explaining things thoroughly but clearly
Nicely done. I teach A&P and this url is going straight into my moodle shell.
Autoregulation also depends on the selective effect of angiotensin on the EFFerent arteriole. Low flow in the DCT triggers renin release from the Juxtaglomerular apparatus, leading to the formation of angiotensin. Angiotensin selectively vasoconstricts the efferent arteriole, bringing the filtration pressure up. Thanks!
the afferent arteriole dilates to keep flow the same--F=deltaP/R where F is inversely proportional to R. So, if pressure increases, R increases and F decreases. Vasodilation of the afferent arteriole adjusts for that. Vasoconstriction would increase pressure further, reducing flow rate even more.
How could anyone NOT like this explanation? Probably clicked thumbs down accidentally!!!!!!

this was so helpful, thanks so much!

Wouldn't the Afferent arteriole vasoconstrict to keep GFR the same when blood pressure drops and vise versa?

@bgates4 correct

@bgates4 No lol, it will constrict when blood pressure rises and vice versa.

Actually, the narrator left out a very important part about maintaining GFR.
Control of the efferent arteriole! That's probably more important than the afferent arteriole.

@masmddds I agree with you here. This site has a relatively OK explanation about BP and GFR:
