Adaptations of the Lungs
- The lungs contain thousands of small air sacks with alveoli inside to give a large surface area for gas exchange.
About Lungs
- The lungs are found in the thorax.
- The lungs are protected by the rib cage.
- The lungs are 100 times easier to inflate than a balloon.
- Breathing in is called inhaling and breathing out is called exhaling.
- The lungs contain many alveoli that exchange Oxygen and Carbon Dioxide with the blood.
