<prompt> Angiotensinogen is secreted by ?KidneyLungLiverBrain  <response>: Ans. is c i.e., Liver Angiotensinogen a, - globulin is produced in liver and is conveed to angiotensin I A-I with the help of renin which is secreted by juxtaglonierular cells of afferent aerioles of kidney and lacis cells located in the junction between the afferent and efferent aerioles. Angiotensin I is conveed to Angiotensin II A-II by angiotensin conveing enzyme ACE. Which is located primarily on the luminal surface of vascular endothelial cells, especially in lungs.
