- Photo title: Alveolus gas exchange. Diagram of the alveolus in the lungs showing gaseous exchange.
- Author: Aldonagriskeviciene
- Cover photo description:
- These are called alveoli. They inflate when a person inhales and deflate when a person exhales. During gas exchange oxygen moves from the lungs to the bloodstream. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
