The renal veins in the renal circulation, are large-calibre [1] veins that drain blood filtered by the kidneys into the inferior vena cava. There is one renal vein draining each kidney. [citation needed] Each renal vein is formed by the convergence of the interlobar veins of one kidney. [2]
The venous drainage of the kidney large mirrors its arterial supply, except that there are no segmental veins. [4] The stellate veins arise from the capillaries, then drain successively through interlobular veins and interlobar veins until these converge from across the kidney to form the renal vein for that kidney.
The vasa recta of the kidney, (vasa recta renis) are the straight arterioles, and the straight venules of the kidney, – a series of blood vessels in the blood supply of the kidney that enter the medulla as the straight arterioles, and leave the medulla to ascend to the cortex as the straight venules.
The interlobar veins are veins of the renal circulation which drain the renal lobes. [citation needed] They collect blood from the arcuate veins. The interlobar veins unite to form a renal vein. [1] Each interlobar vein passes along the edge of the renal pyramids. [2]
Diagram outlining movement of ions in nephron, with the collecting ducts on the right. The collecting duct system is the final component of the kidney to influence the body's electrolyte and fluid balance. In humans, the system accounts for 4–5% of the kidney's reabsorption of sodium and 5% of the kidney's reabsorption of water. At times of ...
The arcuate vein is a vessel of the renal circulation. It is located at the border of the renal cortex and renal medulla . [ citation needed ] Arcuate veins pass around the renal pyramids at the border between the renal cortex and renal medulla in an arch shape. [ 1 ]
Volume of blood plasma delivered to the kidney per unit time. PAH clearance is a renal analysis method used to provide an estimate. Approximately 625 ml/min. renal blood flow = (HCT is hematocrit) Volume of blood delivered to the kidney per unit time. In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...
The stellate veins are minute [1] veins situated just beneath the fibrous capsule of the kidney. [citation needed] The stellate veins drain the superficial-most portion of the renal cortex. Groups of 5 or 6 stellate veins are arranged in a star-like pattern, converging centrally to drain into an interlobular vein as it penetrates into the renal ...
