In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.
What is renal vein?
Each kidney has a single vein that splits into four sections when it enters the organ: the anterior branch takes blood from the front of the kidney, while the posterior branch takes blood from the back.
The left renal vein is often longer than the right renal vein since the inferior vena cava is on the right side of the body.
The following veins are frequently inserted into the left renal vein since the inferior vena cava is not laterally symmetrical:
- Left suprarenal vein, left gonadal vein, and left inferior phrenic vein (left testicular vein in males, left ovarian vein in females)
- lateral 2nd lumbar vein
- Contrarily, on the right side of the body, these veins empty into the IVC immediately.
