Question

What is the blood pressure at the efferent arteriole compared to the afferent arteriole (higher or lower)?

Answer 1

Answer: Nephron of the kidney need blood supply. This supply is done by the efferent and afferent aterioles in the glomerulus of the kidney.

one arteriole will supply the blood to the kidney --- (afferent arteriole)

Get the blood from the glomerulus of the kidney----- ( efferent arteriole)

higher pressure will be in the efferent arteriole, because there will decreased blood flow when compare to the afferent arteriole.

Efferent arteriole- small size blood vessels

Afferent arteriole- Bigger size blood vessels when compare to efferent arteriole.

And afferent arteriole will have increased blood flow to the kidney because the size of the blood vessels is larger than efferent so there will be lessers amount of blood pressure.

Hence,

The blood pressure in efferent arteriole- High

The blood pressure in afferent arteriole- Low
