b) Hepatic vein
c) Jugular vein
d) Femoral vein

Answer 1

The major vein that drains the kidneys is the renal vein.

Step-by-step explanation:

The renal veins are blood vessels that carry deoxygenated blood from the kidneys back to the circulatory system. Each kidney has a renal vein, and they are a crucial part of the renal circulation. The renal veins connect to the inferior vena cava, a large vein that returns blood to the right atrium of the heart.

The major vein that drains the kidneys is the renal vein. Blood supply from the kidneys flows into each renal vein, which are the largest veins entering the inferior vena cava. The left renal vein is longer than the right renal vein, making the left kidney the primary target for organ donation surgeries.
