Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. 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 are the consequences As blood enters the kidneys?
The renal arteries, which supply blood to the kidneys, can become narrowed or blocked—a condition known as renal artery stenosis. Fatty plaque in the arteries that feed the kidneys poses a danger to the heart and brain.
Does all blood go through the kidneys?
Each kidney is about 4 or 5 inches long, roughly the size of a large fist. The kidneys’ job is to filter your blood. They remove wastes, control the body’s fluid balance, and keep the right levels of electrolytes. All of the blood in your body passes through them several times a day.
Why does blood leaving the kidneys have less oxygen?

What takes blood away from the kidney?
