Final answer:
The renal corpuscle, part of the nephron, has a vascular pole where the glomerular afferent and efferent arterioles are located, allowing blood to enter and leave the glomerulus for filtration.
Step-by-step explanation:
The renal corpuscle has two poles. Where the glomerular afferent and efferent arterioles are found is called the vascular pole. The renal corpuscle, an integral part of the nephron located in the renal cortex, includes the glomerulus, a network of capillaries, and the Bowman's capsule, which encases the glomerulus.
The vascular pole is crucial for the blood supply to the nephron, allowing filtration to occur as blood enters the glomerulus via the afferent arteriole and leaves through the efferent arteriole.
