ANF as we know reduce the Na+ uptake and K+ removal in the distal tubules and it also functions as a Vasodialator (?) But again it says that ANF increases the Glomerular filtrate ? But if it is acting has a Vasoldialator (ie, antagonistic to Vasopressin) how is it increasing the GFR ? Shouldnt it lower the GFR ?
ANF - Atrial Natriuretic Factor also called Atrial Natriuretic Peptide
GFR - Glomerular Filtration Rate
