Arteries that supply the trachea do so via small branches that supply the trachea from the sides. As the branches approach the wall of the trachea, they split into inferior and superior branches, which join with the branches of the arteries above and below; these then split into branches that supply the anterior and posterior parts of the ...
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
The primary role of the bronchomediastinal lymph trunks is to transport lymph, which contains proteins, lipids, and immune cells such as lymphocytes, from the thoracic organs, including the lungs, heart, trachea, and esophagus, to the bloodstream. These trunks act as major conduits for lymph to reach larger lymphatic ducts or directly enter the ...
The lungs together weigh approximately 1.3 kilograms (2.9 lb), and the right is heavier. The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles, which receive air breathed in via the conducting zone. These divide until air reaches microscopic alveoli, where gas exchange takes ...

structures of the nervous system including the paired vagus nerves, and the paired sympathetic chains, lymphatics including the thoracic duct. It contains three potential spaces lined with mesothelium: the paired pleural cavities and the pericardial cavity. The mediastinum comprises those organs which lie in the centre of the chest between the ...
Paratracheal nodes are located on either side of the trachea. Tracheobronchial nodes can be divided into three nodes including left and right superior tracheobronchial nodes, and the inferior trachiobronchial node. The two superior tracheobronchial nodes are located on either side of trachea just before its bifurcation.
The carina of trachea (also: "tracheal carina" [1]) is a ridge [1] of cartilage [2] at the base of the trachea separating the openings of the left and right main bronchi. [ 1 ] [ 2 ] Structure
