===Glomerulus===
{{Main article|Glomerulus (kidney)|l1 = Glomerulus}}

The glomerulus is the network, known as a ''tuft'', of filtering [[capillary|capillaries]] located at the [[Renal corpuscle|vascular pole]] of the renal corpuscle in Bowman's capsule. Each glomerulus receives its blood supply from an [[afferent arterioles|afferent arteriole]] of the [[renal circulation]]. The glomerular blood pressure provides the driving force for water and solutes to be filtered out of the [[blood plasma]], and into the interior of [[Bowman's capsule]], called Bowman's space.

Only about a fifth of the plasma is filtered in the glomerulus. The rest passes into an [[efferent arteriole]]. The diameter of the efferent arteriole is smaller than that of the afferent, and this difference increases the hydrostatic pressure in the glomerulus.
