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 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 ...
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites , and regulate blood pH .
The stellate veins join to form the interlobular veins, which pass inward between the rays, receive branches from the plexuses around the convoluted tubules, and, having arrived at the bases of the renal pyramids, join with the venae rectae.
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] Arcuate veins receive blood from cortical radiate veins, and in turn deliver blood into the arcuate veins. [2]
The typical mammalian kidney consists of a renal capsule, a peripheral cortex, an internal medulla, one or more renal calyces, and a renal pelvis. [7] Although the calyces or renal pelvis may be absent in some species. [7] The medulla is made up of one or more renal pyramids, [8] forming papillae with their innermost parts. [9]
Meanwhile, the filtered blood drains into the renal vein. Prerenal kidney injury is due to a decreased blood flow into the kidneys. It could be due to an absolute loss of body fluid, like with major hemorrhage or blood loss, vomiting, diarrhea, or with severe burns where body fluid evaporates quickly without the protective skin.
