for the air to pass through nasal cavity before it enters the lungs?

Why is nitrogen gas not exchanged between the alveoli and the blood in the lung capillaries?

In the alveoli Multiple Choice   a)no exchange with the blood occurs.   b) oxygen diffuses out of the blood while carbon dioxide diffuses into the blood.   c) oxygen diffuses into the blood while carbon dioxide diffuses out of the blood.   d) both oxygen and carbon dioxide diffuse into the blood.   e) both oxygen and carbon dioxide diffuse out of the blood.

If a person has an injury that punctures the pleural space, what would happen to their ability to breathe and why?

What are the passageways leading from the nose to where oxygen can be absorbed into the blood stream? Explain how both diffusion and convection are necessary to deliver oxygen from the nasal cavity to the cells of the body.
