Each kidney is suppied with blood by a single renal artery that arises on its respective side of the aorta before dividing into five segmental arteries that enter the Highlands within the kinney.
Each segmental artery branches into several lobular arteries. The lobular aeteries futher subdivide to form interlocutor arteries, which branch off into afferent arterioles. Blood flows into the glomerulus line through the afferent arteriole. The afferent and efferent arterioles regulate the glomerular capillary pressure by selectively dilating or constricting. The kidneys venous blood now filtered, flows from the glomerulus via the efferent arterioles into the pair tubular capillary network. A low-pressure reabsorbed system surrounding all protions of the tubules. This arrangement permits rapid movement have cell youth and water between the fluid in the tubular lumen and the blood inthe capillaries. The Pair tubular capillaries rejoined to form the venous channels, by which blood leaves the kidneys and empties into the inferior vena cava.
