Renal Physiology
Renal PhysiologyThe kidneys receive a large volume of blood, around 1200 mL/min or approximately 20% of cardiac output. The renal artery branches from the abdominal aorta at the level of the intervertebral disc between L1 and L2. One renal artery supplies each kidney, and the right renal artery usually originates slightly lower than the left.Each renal artery divides into anterior and posterior branches. Afferent arterioles branch from small arteries in the cortex and each afferent arteriole carries blood to the glomerulus. Blood leaves the glomerulus through efferent arterioles.The glomerulus is an arterial capillary tuft sandwiched between two arterioles. The efferent arteriole leads to a peritubular capillary network entwined around the r…
