The Intrapulmonary nodes or Lymphatic Vessels of the Lungs originate in two plexuses, a superficial and a deep.
In the smaller bronchi there is but a single plexus, which extends as far as the bronchioles, but fails to reach the alveoli, in the walls of which there are no traces of lymphatic vessels.
The superficial efferents turn around the borders of the lungs and the margins of their fissures, and converge to end in some glands situated at the hilus; the deep efferents are conducted to the hilus along the pulmonary vessels and bronchi, and end in the tracheobronchial lymph nodes.
Little or no anastomosis occurs between the superficial and deep lymphatics of the lungs, except in the region of the hilus.
they are located in right fissure of lung near the heart This article incorporates text in the public domain from page 719 of the 20th edition of Gray's Anatomy (1918)
