In the literature anatomic variations of the renal arteries are described variously as extra additional supernumerary aberrant anomalous or incidental renal arteries as well as superior and inferior polar arteries arising from the aorta or simply polar arteries. For instance renal failure is a failure of the kidneys.

The renal artery is one of these two blood vessels.
Renal artery anatomy. Each is directed across the crus of the diaphragm so as to form nearly a right angle. Renal comes from the latin word for kidney. Renal artery one of the pair of large blood vessels that branch off from the abdominal aorta the abdominal portion of the major artery leading from the heart and enter into each kidney.
Renal papilla lead from collecting ducts to minor calyces merge into several extensions called major calyces form a flat funnel shaped tube that is continuous to the ureter. After travelling through the hilum the renal artery divides generally within two large. Each minute the kidneys receive 20 of the blood pumped by the heart.
Under normal circumstances once the renal artery enters through the hilum it splits into two main branches which each then split into numerous smaller arteries. Renal artery bypass surgery. Renal artery is among the pair of large blood vessels that expand via the abdominal aorta and participate in each kidney.
In medicine and anatomy the word renal refers to anything related to the kidney. Renal artery branches off of the aorta bringing waste filled blood into the kidney for filtering in the nephrons. During a bypass procedure doctors graft a substitute blood vessel to the renal artery to make a new route for blood to reach your kidneys.
Any variant in arterial supply is important to clinicians undertaking surgery or other interventional renal procedures. The kidneys are two bean shaped organs that remove waste substances from the blood and aid in fluid conservation and in stabilization. Often the words we use as scientific terms especially medical terms are based on latin words.
The renal arteries originate from the abdominal aorta and enter the renal hila to supply the kidneys. The renal artery is further subdivided into several branches inside the kidney. The renal artery enters through the hilum which is located where the kidney curves inward in a concave shape.
Sometimes this means connecting the renal artery to a vessel from somewhere else such as the liver or spleen. Calyces are contained in the pelvis. The renal arteries carry a large portion of total blood flow to the kidneys.
At the inner concavity of every kidney there is an entrance referred to as the hilum through that the renal artery enters. Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys.
