What are the afferent and efferent arterioles?
Explanation: The afferent arteriole is the arteriole that brings blood to the glomerulus. It is larger in diameter than the efferent arteriole. The efferent arteriole is the arteriole that carries blood away from the glomerulus.Click to see full answer.

Explanation: The afferent arteriole is the arteriole that brings blood to the glomerulus. It is larger in diameter than the efferent arteriole. The efferent arteriole is the arteriole that carries blood away from the glomerulus.Click to see full answer. In this regard, what is the difference between the afferent and efferent arterioles?The main difference between afferent and efferent arterioles is that afferent arterioles carry blood to the glomerulus whereas efferent arterioles take the blood away from the glomerulus. An afferent arteriole is a branch of the renal vein, which carries blood containing nitrogenous wastes.Subsequently, question is, why is the efferent Arteriole smaller than the afferent Arteriole? The efferent arteriole carries blood away from the glomerulus. Because it has a smaller diameter than the afferent arteriole, it creates some resistance to blood flow, producing the back-up of blood in the glomerulus which creates higher pressure in the glomerular cavity. Also to know is, what dilates the afferent Arteriole? Constriction of the afferent arterioles has two effects: it increases the vascular resistance which reduces renal blood flow (RBF), and it decreases the pressure downstream from the constriction, which reduces the GFR. Dilation of the afferent arterioles has the opposite effects.Where is the afferent Arteriole located?The afferent arterioles branch from the renal artery, which supplies blood to the kidneys. The afferent arterioles later diverge into the capillaries of the glomerulus.
