Term
What happens to the Efferent arterioles and smooth muscle cells when Angiotensin II causes the release of ADH? |
|
Definition
Efferent artioles- vasocontriction which increases GFR Smooth muscle cells- constrict to increase blood pressure which increases GFR |

|
Definition
A symporter has a miximum amount for transport measured so if a substance is above Tm, it gets urinated |
