The distribution and ultrastructural morphology of lymphatic vessels in the canine renal cortex.

Abstract

Ultrastructural observations were made of canine renal cortical lymphatic vessels following specific labeling. The major findings were I) the large number of the discreete openings in the lymphatic among arteries, veins, tubules and Bowman's capsules and 3) the disreet openings in the lymphatic endothelial wall. It is concluded that the renal cortex contains a significant lymphatic plexus and that cortical lymph may be derived from a variety of intrarenal structures.
