The cells stimulated include the white blood cells known as monocytes, neutrophils and natural killer cells and the epithelial cells that line the respiratory tract (nose, tracheobronchial tree and lungs).
There are three basic regions to the respiratory tract: nasopharyngeal region; tracheobronchial region; and pulmonary region.
Particles 2-5 µM can penetrate into the tracheobronchial region.
The Lymphatic Vessels of the Thymus end in the anterior mediastinal, tracheobronchial, and sternal glands.
It ascends in the posterior longitudinal sulcus and then runs forward in the coronary sulcus, and passes up behind the pulmonary artery, to end in one of the tracheobronchial glands.
Their efferents mostly end in the thoracic duct, but some join the tracheobronchial glands.
The afferents of the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and the heart; some of the efferents of the posterior mediastinal glands also end in this group.
On reaching the coronary sulcus they are joined by a large trunk from the diaphragmatic surface of the heart, and then unite to form a single vessel which ascends between the pulmonary artery and the left atrium and ends in one of the tracheobronchial glands.
The visceral lymph glands consist of three groups, viz.: anterior mediastinal, posterior mediastinal, and tracheobronchial.
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 glands.
