Question

Quizplus · Accepted Answer

Atrial natriuretic peptide increases glomerular filtration rate (GFR) by dilating the afferent arteriole and constricting the efferent arteriole, which results in increased blood flow into the glomerulus and increased filtration. It also inhibits the release of renin by the juxtaglomerular cells of the kidney, which reduces the production of angiotensin II and aldosterone, leading to decreased sodium and water reabsorption, and more urine output.
