All the following are true regarding blood supply to the kidney, EXCEPT?
Blood supply to the kidney: The renal aery arises from the aoa at the level of the second lumbar veebra. Each renal aery usually divides into five segmental aeries that enter the hilum of the kidney. Lobar aeries arises from each segmental aery, one for each renal pyramid. Each lobar aery gives off two or three interlobar aeries. The interlobar aeries run toward the coex on each side of the renal pyramid. At the junction of the coex and the medulla, the interlobar aeries give off the arcuate aeries, which arch over the bases of the pyramids. The arcuate aeries give off several interlobular aeries that ascend in the coex. The afferent glomerular aerioles arise as branches of the interlobular aeries. Venous drainage: The renal veins arise from three sources venae stellate, interlobular veins and venae rectae.
It is a type of poal-circulation
Stellate veins drain superficial zone
Its segmental aeries are end-aeries
The renal aery divides into five segmental aeries before entering the hilum
