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]
After filtration occurs, the blood moves through a small network of venules that converge into interlobular veins. As with the arteriole distribution, the veins follow the same pattern: the interlobular provide blood to the arcuate veins then back to the interlobar veins, which come to form the renal vein exiting the kidney for transfusion for ...
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]
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 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.
The renal sinus is a cavity within the kidney which is occupied by the renal pelvis, renal calyces, blood vessels, nerves and fat. The renal hilum extends into a large cavity within the kidney occupied by the renal vessels, minor renal calyces, major renal calyces, renal pelvis and some adipose tissue. [1]

The kidney is well supplied with lymphatic vessels, [114] which remove excess fluid with substances and macromolecules dissolved in it from the interstitium that fills the space between the tubules and blood vessels. [115] [116] The anatomy of the lymphatic system of the kidney is similar between mammals. [117]
