Blood enters the kidneys through the renal artery, which is a branch of the aorta.
Blood Flow Into the Kidneys Explained
Here's a breakdown of how blood enters and flows through the kidneys, based on the reference provided:
- Renal Artery: Each kidney receives its blood supply directly from the renal artery, a major vessel branching off the aorta.
- Smaller Arteries: The renal artery then branches into progressively smaller arteries within the kidney.
- Arterioles: These smaller arteries eventually lead to arterioles, which are even smaller vessels.
- Glomeruli: Blood then flows from the arterioles into the glomeruli. The glomeruli are networks of microscopic blood vessels called capillaries.
Essentially, the blood's entry point is the renal artery, which then delivers blood throughout the kidney's filtration system.
