WebThe afferent arteriole is the incoming blood vessel that supplies blood to the glomerulus of the nephron and helps to regulate blood pressure within the kidneys. The diameter of the afferent arteriole is wider than that of the efferent arteriole. Therefore, blood that passes through the glomerulus is forced to exit through a narrower tube.
