What is An impoant non-respiratory function of Lungs is: and explain in detail?
Lung has large amounts of angiotensin conveing enzyme which is located on the surface of endothelial cells of the pulmonary capillary. This enzyme conves the inactive decapeptide angiotensin I into aldosterone stimulating octapeptide angiotensin II. This angiotensin II stimulates the production of aldosterone which increase sodium resoption, thereby maintaining sodium balance.
