Drains to arcuate veins

The straight venules of kidney are branches from the plexuses at the apices of the medullary pyramids, formed by the terminations of the arteriae rectae.

They run outward in a straight course between the tubes of the medullary substance, and joining, as above stated, the interlobular veins, form venous arcades; these in turn unite and form veins which pass along the sides of the pyramids.

Contains fenestrated capillaries.
