Question

Compare and contrast the blood composition in the renal artery and the renal vein.

Accepted Answer

Feature Renal artery Renal vein

Blood composition: Oxygen and carbon dioxide The renal artery is a type of artery that provides oxygenated blood to the kidney. Thus, the concentration of oxygen is more, and carbon dioxide gas (due to respiration) is less in the renal artery. A renal vein is a type of vein through which deoxygenated blood leaves the kidney. Thus, the concentration of oxygen is less, and carbon dioxide is more in the renal vein.

Feature Renal artery Renal vein

Blood composition: Urea The renal artery contains more urea as the blood has not been filtered. The renal vein consists of low urea as a large amount of urea is filtered out through the glomerulus of nephrons.

Feature Renal artery Renal vein

Blood composition: Water and other solutes As the renal artery is supplying blood to the kidney, the blood in it must have more water, solutes and ions. As the renal vein is leaving the kidney, it must have low water, solute and ions because some of these are released through urine via different processes conducted in the nephron.
