BRAINCAKEGlomerulus
The glomerulus is a network of capillaries with many gaps between the capillary endothelial cells.
Blood flows under hydrostatic pressure into the capillaries through the afferent arteriole, a branch of the renal artery, and flows out of the glomerulus through the efferent arteriole.

Key terms in this lesson
- Bowman's capsule
- The cup-shaped structure at the start of a nephron that encloses the glomerulus and collects the filtrate produced during ultrafiltration.
- ultrafiltration
- The filtration of blood plasma under high hydrostatic pressure through the capillary walls, basement membrane and podocytes of the Bowman's capsule, producing a filtrate free of large proteins and cells.
