GENERAL HISTOLOGY

Detailed explanation-1: -The kidney receives the oxygenated blood through the renal artery. The kidney transports the deoxygenated blood through the renal vein. Since the renal vein carries deoxygenated blood, Carbon dioxide is present in a lower concentration in the renal artery than in the renal vein.

Detailed explanation-2: -Renal Veins carry filtered blood from the kidneys to the posterior vena cava. Renal Arteries carry unfiltered blood from the aorta to the kidneys.

Detailed explanation-3: -Oxygenated blood comes to the kidneys from the right and left renal arteries off the abdominal aorta. Deoxygenated blood leaves the kidneys via the right and left renal veins that run into to the inferior vena cava.

Detailed explanation-4: -The renal artery brings blood to the kidney for filtration whereas the renal vein carries away filtered blood from the kidney. The renal artery takes blood to the kidney. The renal vein takes blood away from the kidney. In the kidney, the waste product urea is filtered out of the blood..

Detailed explanation-5: -Thus, renal artery has more urea than renal vein.
