The kidneys are vital to the body’s production of urine. They also play a function in regulation important materials in the blood.

You are watching: What vessel returns filtered blood to the inferior vena cava


Oxygenated blood comes to the kidney from the right and also left renal arteries turn off the abdominal muscle aorta. Deoxygenated blood pipeline the kidneys via the right and left renal veins the run into to the inferior vena cava.


The kidneys space highly complicated “filtration factories.” inside each kidney, the renal arteries branch into smaller and also smaller components until castle make contact with the core structural and also functional devices of the kidney, the nephrons.

The nephrons include tiny coiled tube of capillaries and their connected tubules. Every kidney has approximately 1 million that them. The nephrons control waste, water, and other products in the blood and also urine to readjust to the body’s an altering needs.


Other crucial parts of the kidney include:

Renal pyramids: cone-shaped lobes consist of of parallel segment of nephronsCalyx: cup-like frameworks that assist collect urine indigenous the hilar tip of each renal pyramid top top its method to the renal pelvisRenal pelvis: funnel-shaped, an initial portion the the ureter in the kidneyHilum: the ar that’s the entry and also exit clues of the kidney for the renal veins, renal arteries, and ureter situated on the medial side of the kidney

Within each nephron is a small sac of capillaries dubbed the glomerulus that’s surrounding by Bowman’s capsule.


In this capillaries, under chop pressure, materials are constantly gift filtered out of the blood. The push in every glomerulus is higher than in any kind of other capillary. Each glomerulus demands that push to proactively filter international particles out of the body.


Because the their require for high pressure, the kidney also help control blood press by creating renin.

Renin helps increase the blood pressure and retain sodium in the bloodstream, which leader to water retention. Both the result arterial constriction and sodium and water retention assist restore common blood press if that dips.

The kidneys additionally regulate the manufacturing of red blood cells. As soon as the kidney don’t get sufficient oxygen, their distress contact comes in the form of production of erythropoietin. Erythropoietin is a hormone the stimulates the bone marrow come produce more oxygen-carrying red blood cells.

After the kidneys have actually performed your cleansing function, the filtered, deoxygenated blood pipeline the kidneys through the renal vein, move up the worse vena cava, and also returns come the heart.
