Description
The veins of the respiratory system do not refer to the pulmonary system, but to the systemic system that provides oxygenated blood and nutrition to the connective tissue of the lungs. These include the highly variable bronchial veins.
A left and right bronchial vein arise from the posterior surface of the bronchi. These veins travel posteriorly to their terminations at the azygos vein on the right and the hemiazygos vein, or sometimes the superior intercostal vein, on the left.
The bronchial veins receive blood from the bronchi, hilar structures, such as lymph nodes, and visceral pleura adjacent to the hilum.

Respiratory System
The respiratory system is a general term for a series of organs that exchange gas between the human body and outside air, including the nose, pharynx, larynx, trachea, bronchus, and lung, which are composed of many alveoli, blood vessels, lymphatic vessels, nerves, pleura, and other tissues [1].
