|
The afferent and efferent arterioles are the same width
|
Explanation:
Detailed explanation-1: -The afferent arteriole larger in diameter than the efferent arteriole; This is to provide for the increased blood pressure in the glomerulus for ultrafiltration to take place.
Detailed explanation-2: -Afferent arterioles bring blood into your kidney’s glomerulus (blood vessels that filter your blood). Afferent arterioles can dilate, or get wider, to allow for more filtration. Efferent arterioles take blood out of your glomerulus. Arterioles in your lungs constrict or tighten when there’s not enough oxygen.
Detailed explanation-3: -The efferent arteriole has a narrower lumen (lesser diameter) than that of afferent arteriole.
