Q
Pathogenesis of renal artery stenosis ??
P-67
A
=dec blood to glomeruli
=JGA secrete Renin
=Renin === Angiotensinogen—-Angiotensin 1
= ATI —- AT II by ACE
= ATII inc BP **
2
Q
How ATII inc BP ??
P-67
A
- contract arteriolar smooth muscle = inc TPR
- Adrenal release of aldosterone = inc reabsoprtion of Na in DCT

- Headache
- Papilledema
3
Q
