where is the glomerulus located in the nephron
Glomerulus (kidney) The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney.[2] Glomerular mesangial cells structurally support the tufts. Blood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole.[3] The capillaries consist of a tube lined by endothelial cells with a central lumen. The walls have a unique structure: there are pores between the cells that allow water and soluble substances to exit, and after passing through the glomerular basement membrane, and between podocyte foot processes, enter the capsule as ultrafiltrate.
