                        To whom it may concern:  I wanted to know if you could tell me the biology behind a collasped lung.  And also the casues and affects.  I have a friend who has one and I needed to give her some information about it.  I wlso wantd to know if because she has had a history of pneumonia or bronchitis could have an affect on her having a collapsed lung?   Thank you for taking the time to read my request.
