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
Suprascapular artery suprasternal branch, which crosses over the sternal end of the clavicle to the skin of the upper part of the chest; and an acromial branch, which pierces the trapezius and supplies the skin over the acromion, anastomosing with the thoracoacromial artery. Just as with supplying the subclavius muscle, it anastomoses with the thoracoacromial artery in supplying skin areas. As the artery passes over the superior transverse scapular ligament, it sends a branch into the subscapular fossa, where it ramifies beneath the subscapularis, and anastomoses with the subscapular artery and with the dorsal scapular artery. It also sends articular branches to
