The kidney vessels

Renal arteries and veins · arteriae et venae renales

The vessels that carry blood into and out of the kidneys.

What it does

Each renal artery branches from the aorta and enters a kidney, splitting into many smaller vessels that feed the kidney's filters. Each renal vein carries the filtered blood back to the inferior vena cava.

Surprising fact

The kidneys receive around a fifth of the blood pumped by your heart, far more than their size would suggest, because their job is to filter it.

Why it matters

A narrowed renal artery can raise blood pressure, because the kidney mistakes the poor flow for low blood pressure and releases hormones to push it up.
