I am totally mixed up right now. Please help me!
Does angiotensin2 contract afferent or efferent arteriole of the glomerulus? In some writings, it says that in the case of blood loss, the renal blood flow decreases therefore raa system is activated to contract the afferent arteriole and prevent more loss. However in some writings about AKI, it says that when ace inhibitor is used, the function of angiotensin2 to contract the efferent arteriole is decreased so gfr is decreased and therefore the kidney is damaged..
1. What happens to the raa system when blood loss occurs?
2. What does angiontensin2 do to the afferent and efferent arteriole?
