Trachea suppose to be in the center and if it goes on the other side it means it is displaced to other side. Its like establishing pushed or pulled by a disease process. Anything that increases pressure or volume in one hemithorax will push the trachea and mediastinum away from that other side. Any disease causes volume loss in one hemithorax will pull the trachea over towards the other side.
Lungs A bleb is due to the rupture of the wall of the alveolus, allowing air to escape into the alveolar layer of the pleura. With a bulla, there is distention of the alveoli with atrophy, followed by rupture and the formation of an unusually large air filled cavity. Blebs and bullae can be single, multiple, small or distended enough to occupy an entire hemithorax. Frequently bilateral and usually associated with a generalized pulmonary emphysema. Note: The majority of emphysematous blebs are caused by cigarette smoking.
The pleura is a slick, wet, shiny membrane. It is the outer most layer of tissue surrounding the lungs and also the inner most layer of tissue coating the chest wall. The pleura provide well lubricated surfaces of the chest wall and lungs to contact each other with minimal friction during respiration.
