Lymphatics

Lymphatic vessels arise from a plexuses deep within the capsule and in the medulla only. The lymph vessels follow the central vein and the main venous tributaries throughout the medulla of the adrenal gland. Lymphatic plexuses drain to para-aortic and renal lymph nodes.

There is no lymphatic supply to the cortex of the adrenal.
