Blood enters the kidney through the renal artery, which branches to form smaller vessels, each of which eventually leads to a bundle of capillaries called a glomerulus. Glomerulus is a tuft of capillaries fitted in the cavity of Bowman's capsule. The glomerulus receives its blood supply from an afferent arteriole of the renal artery. The glomerular blood pressure provides the driving force for fluid and solutes to be filtered out of the blood and into the space made by Bowman's capsule. The remainder of the blood not filtered into the glomerulus passes into the narrower efferent arteriole. The afferent arteriole supplies blood to the glomerulus. whereas the efferent arteriole drains the glomerulus.
