If the pleural space lost its negative pressure, which of the following would be true?

A. Inspiration would be more difficult.
B. Expiration would be more difficult.
C. Surfactant wouldn’t be needed.
D. Exchange of oxygen and carbon dioxide would improve.

A, because your lungs at rest/exhaled before inhalation is at a negative pressure. When you breath in air from the outside has a tendency to move into your lungs because the air pressure in your lungs is lower than the outside air pressure that’s how we breathe in. A lost of negative pressure then would render inspiration to be more difficult.
