Afferent Arteriole


Kid.AfA
The afferent arteriole is an arteriole that feeds blood into the glomerulus. The renal arterioles play a central role in determining glomerular hydraulic pressure, which facilitates glomerular filtration.The afferent arterioles modulate their vascular resistance in response to changes in intraluminal pressure or composition of tubular fluid at the macula densa. In this manner, they control the glomerular filtration.

In the mouse kidney, first arterioles are seen within 15-16 days of gestation. Maturation of kidney vasculature continues after birth.
