Alveoli and gas exchange
Biology · Secondary 3 · Medium · Alveoli and gas exchange
Pulmonary edema causes fluid to fill the alveoli. How does this affect gas exchange between the air in the alveoli and the blood?
- It increases the surface area for gas exchange, so more oxygen enters the blood.
- It decreases the diffusion distance, so gas exchange becomes faster.
- It increases the diffusion distance, so less oxygen enters the blood.
- It warms the air, so more carbon dioxide diffuses into the alveoli.
