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
End artery liver, kidneys, spleen and intestines; they may also exist in the heart. IMPORTANCE OF END ARTERIES :- Occlusion of an end-artery causes serious nutritional disturbances resulting in death of the tissue supplied by it. For example, occlusion of central artery of retina results in blindness. The results are severe because the blood flow to that region is completely stopped since there is no collateral circulation. End artery An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Arteries which do not anastomose with their neighbors are called end
