Which type of peptide increases glomerular filtration and renal excretion of sodium and water?

Atrial natriuretic peptide (ANP) is a hormone produced by the heart in response to increased blood volume and pressure. Its primary function is to promote natriuresis, which is the excretion of sodium through the urine. ANP achieves this by acting on the kidneys, leading to increased glomerular filtration rate (GFR) and promoting the excretion of sodium and water.

When ANP is released, it causes relaxation of afferent arterioles and constriction of efferent arterioles in the kidneys, resulting in increased blood flow into the glomeruli. This enhanced blood flow leads to an increase in GFR, allowing for greater filtration of plasma and subsequently more sodium and water to be excreted. Additionally, ANP inhibits the secretion of renin, aldosterone, and other factors that typically promote sodium retention and water reabsorption, further promoting the excretion process.

The other options refer to hormones with different functions. Vasopressin (also known as antidiuretic hormone) primarily decreases urine output by promoting water reabsorption in the kidneys. Aldosterone is involved in sodium retention and water reabsorption, while renin is an enzyme that starts a cascade leading to
