Interlobular arteries
Encyclopedia
The first set of renal bloodvessels, the interlobular arteries (or cortical radiate arteries, or cortical radial arteries), are given off at right angles from the side of the arcuate arteries looking toward the cortical substance, and pass directly outward between the medullary rays
to reach the fibrous tunic, where they end in the capillary network of this part.
These vessels do not anastomose with each other, but form what are called end-arteries.
In their outward course they give off lateral branches; these are the afferent vessels
for the renal corpuscles; they enter the capsule, and end in the glomerulus
.
From each tuft the corresponding efferent vessel arises, and, having made its egress from the capsule near to the point where the afferent vessel enters, breaks up into a number of branches, which form a dense plexus within Bowman's capsule

Medullary ray (anatomy)
In anatomy, the medullary ray is the middle part of the cortical lobule or renal lobule, consisting of a group of straight tubes to the collecting ducts.Their name is potentially misleading -- the "medullary" refers to their destination, not their location...

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....

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...

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...
