What is the difference between the efferent arteriole and afferent?

Afferent and efferent arterioles are responsible for the supply of blood to the glomerulus of the kidney. An afferent arteriole is a branch of the renal vein, which carries blood containing nitrogenous wastes. An efferent arteriole is a branch of the renal artery, which carries filtered blood back to the circulation.

Difference between the efferent arteriole and afferent arteriole

The difference between the efferent arteriole and afferent arteriole is tabulated below

Afferent Arteriole Efferent arteriole
Afferent arterioles are branches of the renal vein, approaching the proximal portion of the nephron. Efferent arterioles are branches of the renal artery, approaching the distal portion of the nephron.
Afferent arteriole carries blood to the glomerulus. Efferent arteriole takes blood away from the glomerulus.
Afferent arteriole is a branch of the renal vein. Efferent arteriole is a branch of the renal artery.
The blood carried by the afferent arteriole contains nitrogenous wastes. The blood in the efferent arteriole lacks nitrogenous wastes.
The blood of the afferent arteriole contains water, blood cells, platelets, glucose, amino acids, ions, and nitrogenous wastes. The blood of the efferent arteriole contains less water, glucose, amino acids, ions, and nitrogenous wastes
Afferent arterioles maintain the blood pressure. Efferent arterioles maintain the glomerular filtration rate.
Afferent arteriole contains blood with high pressure. The pressure of the blood in the efferent arteriole is less than that of the afferent arterioles.
