vascular pole

The vascular pole is an anatomical feature of the renal corpuscle in the kidney. It is the opening where blood vessels, specifically the afferent and efferent arterioles, enter and exit the glomerulus, which is a cluster of capillaries enclosed within Bowman's capsule. This is where blood enters and leaves the glomerulus, playing a crucial role in the filtration process that initiates urine production. The juxtaglomerular apparatus, involved in renin secretion, is also located near the vascular pole. In plants, vascular tissue is organized into discrete strands called vascular bundles, containing xylem and phloem, which are responsible for transporting water, minerals, and food throughout the plant.123
