The afferent arteriole and efferent arteriole feed blood into and out of the Bowman's capsule. The afferent arteriole transports blood from the interlobular artery to the capsule to be filtered. The efferent arteriole transports the filtered blood from the capsule to the medullary plexus, and then to the interlobular vein.
 Research Afferent Arteriole
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.
Research Glomerulus
The intralobular artery and vein are the intermediate blood vessels which carry blood to and from the nephron. The artery introduces blood to the Bowman's capsule via the afferent arteriole. The efferent arteriole carries the filtered blood from the capsule, through the medullary plexus, and back to the intralobular vein.
Research Intralobular Artery and Vein
The medullary plexus is the fine network of blood capillaries within the nephron. These capillaries are the constricting demarcation between the intralobular artery and vein.
