The glomerulus is the main filter of the |nephron| and is located within the |Bowman's capsule|. The glomerulus resembles a twisted mass of tiny tubes through which the ~blood~ passes. The glomerulus is semipermeable, allowing water and soluble wastes to pass through and be excreted out of the |Bowman's capsule| as ~urine~. The filtered ~blood~ passes out of the glomerulus into the efferent |arteriole| to be returned through the |medullary plexus| to the |intralobular| |vein|.
