GENERAL HISTOLOGY

Detailed explanation-1: -The main blood vessel that carries blood from the kidney and ureter to the inferior vena cava (a large vein that carries blood to the heart from the lower part of the body). There is a renal vein for each kidney.

Detailed explanation-2: -The substances removed from the blood form urine. The cleaned blood then travels to the heart and is pumped to the rest of the body.

Detailed explanation-3: -The renal vein takes purified blood away from the kidney to reach the inferior vena cava. There are two renal veins in the human body. The inferior vena cava is the largest vein that pours deoxygenated blood into the heart.

Detailed explanation-4: -After the kidneys have performed their cleansing function, the filtered, deoxygenated blood leaves the kidneys through the renal vein, moves up the inferior vena cava, and returns to the heart.
