Vascular pole
Encyclopedia
The vascular pole is a location of the glomerulus
. At the vascular pole, the afferent arterioles
and efferent arterioles enter the Bowman's capsule
.
The urinary pole
is at the other end.
Glomerulus
A glomerulus is a capillary tuft that is involved in the first step of filtering blood to form urine.A glomerulus is surrounded by Bowman's capsule, the beginning component of nephrons in the vertebrate kidney. A glomerulus receives its blood supply from an afferent arteriole of the renal...

Afferent arterioles
The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems. They play an important role in the regulation of blood pressure as a part of the Tubuloglomerular feedback mechanism....

Bowman's capsule
The Bowman's capsule is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine. A glomerulus is enclosed in the sac...
