Renal artery kidneys leading to reduced kidney function and, possibly, renal failure. Renal artery The renal arteries normally arise off the left interior side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle. The renal arteries carry a large portion of total blood flow to the kidneys. Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys. It has a radius of approximately 0.25 cm, 0.26 cm at
Cystic artery equivalent of the posterior branch. It must be identified and ligated in operations that remove the gallbladder (cholecystectomies). Cystic artery The cystic artery (also known as bachelor artery) supplies oxygenated blood to the gallbladder and cystic duct. In the classic arrangement, occurring with a frequency of approximately 70%, a singular cystic artery originates from the geniculate flexure of the right hepatic artery in the upper portion of the hepatobiliary triangle. A site of origin from a more proximal or distal portion of the right hepatic artery is also considered relatively normal. After separating from the right hepatic artery, the cystic
