because the lungs can not re-inflate themselves
why? there is a very delicate balance of pressures in are lung, the plueral sac, and in our thoracic cavity that must be maintained. if the balance is offset then our lungs simply wont function properly. im not exactly sure what a doctor does when they insert a tube into the chest to re inflate the lung, but im certain that it is to restore the pressures of the different cavities in the chest
The doctor will make an incision under the arm, to insert a chest tube. This chest tube will drain off any blood in the lungs, allowing it to re inflate.
Your lungs are in the thoracic cavity, which includes the chest down to the diaphragm. The lungs are located on both sides of the heart in pleural cavities.Source:http://www.dummies.com/how-to/content/what-is-in-the-thoracic-cavities.html
No, birds have lungs in their chest cavity not their wings.

In your chest.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
When the chest cavity becomes larger, the lungs expand to fill the space. This expansion allows for more air to enter the lungs during inhalation, increasing the oxygen supply to the body. Conversely, when the chest cavity shrinks, the lungs compress and force air out during exhalation.
A bronchide is when your chest the lungs are infected.
