The renal veins drain the kidney and the renal arteries supply blood to the kidney.
Detail the blood and nerve supply of the kidney
The renal arteries branch off of the abdominal aorta and supply the kidneys with blood. The arterial supply of the kidneys varies from person to person, and there may be one or more renal arteries supplying each kidney.
The renal veins are the veins that drain the kidneys and connect them to the inferior vena cava.
The kidney and the nervous system communicate via the renal plexus. The sympathetic nervous system will trigger vasoconstriction and reduce renal blood flow.
Because the kidney filters blood, its network of blood vessels is an important component of its structure and function. The arteries, veins, and nerves that supply the kidney enter and exit at the renal hilum.
The renal arteries branch off of the abdominal aorta and supply the kidneys with blood. The arterial supply of the kidneys is variable from person to person, and there may be one or more renal arteries supplying each kidney. Due to the position of the aorta, the inferior vena cava, and the kidneys in the body, the right renal artery is normally longer than the left renal artery. The renal arteries carry a large portion of the total blood flow to the kidneys, up to a third of the total cardiac output can pass through the renal arteries to be filtered by the kidneys.
Renal blood supply starts with the branching of the aorta into the renal arteries (which are each named based on the region of the kidney they pass through) and ends with the exiting of the renal veins to join the inferior vena cava. The renal arteries split into several segmental arteries upon entering the kidneys.
Each segmental artery splits further into several interlobar arteries and enters the renal columns, which supply the renal lobes. The interlobar arteries split at the junction of the renal cortex and medulla to form the arcuate arteries. The arcuate "bow shaped" arteries form arcs along the base of the medullary pyramids. Cortical radiate arteries, as the name suggests, radiate out from the arcuate arteries. The cortical radiate arteries branch into numerous afferentarterioles, and then enter the capillaries supplying the nephrons.
The renal veins are the veins that drain the kidneys and connect them to the inferior vena cava. The inferior vena cava is on the right half of the body, and as such, the left renal vein is generally the longer of the two. Unlike the right renal vein, the left renal vein often receives the left gonadal vein (left testicular vein in males, left ovarian vein in females). It frequently receives the left suprarenal vein as well.
The kidneys receive blood from the renal arteries which branch into segmental arteries and into interlobar arteries that penetrate the renal capsule and extend through the renal columns between the renal pyramids, left and right, which branch directly from the abdominal aorta.

renal arteries carrying total cardiac output to be filtered and returned via renal veins, renal veins (branch off inferior vena cava); blood leaves via renal arteries and abdominal aorta, renal veins; due to kidney position, right one is longer than leftt; vice versa in renal arteries, and renal arteries (branch off the abdominal aorta); blood leaves via renal veins and inferior vena cava
