The azygos vein is unpaired in that there is only one in the body, mostly on the right side. While there is the hemiazygos vein and its accessory on the left side of the body, they are considered tributaries of the azygos vein rather than its left-side equivalent. This terminology is only accurate in some species, such as the human, dog, and cat.
The hemiazygos vein and the accessory hemiazygos vein, when taken together, essentially serve as the left-sided equivalent of the azygos vein. [2] That is, the azygos vein serves to drain most of the posterior intercostal veins on the right side of the body, and the hemiazygos vein and the accessory hemiazygos vein drain most of the posterior intercostal veins on the left side of the body.

The right bronchus makes an angle of 25°, while the left one makes an angle of 45°. The carina is a sensitive area. When the patient is made to lie on their left side, secretions from the right bronchial tree flow toward the Carina due to the effect of gravity.

Dr. Wasan shares that there are several organs located on the right side of the body that can cause pain, including the lungs, gallbladder, pancreas, appendix, colon or even kidneys.
Right-side chest pain may be a sign of something less worrisome, like muscle pain. Or it may indicate a more serious health problem related to the heart or lungs.
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
The root of the right lung lies behind the superior vena cava and part of the right atrium, and below the azygos vein.That of the left lung passes beneath the aortic arch and in front of the descending aorta; the phrenic nerve, pericardiacophrenic artery and vein, and the anterior pulmonary plexus, lie in front of each, and the vagus nerve and posterior pulmonary plexus lie behind.
