What is Which causes raised angiotensin in blood -a) Increased blood volumeb) Raised cardiac outputc) Decreased blood pressured) Increased sympathetic tone and explain in detail?
Function of Renin is to convert Angiotensinogen to Angiotensin I. So whenever Renin secretion is increased, Angiotensin I level also increases. Factors which reduce GFR or reduce Na+ delivery to distal tubule causes Renin secretion. Reduced BP or increased sympathetic tone reduces GFR.
