2021年9月13日 · The renal arteries carry a large volume of blood from the heart to the kidneys. The kidneys filter waste and excess fluid from the blood. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.

Your subclavian vein helps move oxygen-poor blood from your upper body back to your heart. It receives blood from your axillary vein and runs under your collarbone.

The renin-angiotensin-aldosterone system (RAAS) is the system of hormones, proteins, enzymes and reactions that regulate your blood pressure and blood volume. Locations : Abu Dhabi | Canada | Florida | London | Nevada | Ohio |
