4. Forced expiration

Q. There are various forms of pneumonia that tend to cause an excessive build-up of mucus in the lungs. What is the effect of this occurrence on the diffusion of gases?

1. Oxygen doesn’t easily diffuse into the blood but carbon dioxide can easily diffuse out

3. Oxygen easily enters the blood but carbon dioxide can’t diffuse out easily
4. Oxygen doesn’t easily diffuse into the blood and carbon dioxide can’t diffuse out easily
