What do the lungs look like and how do they work? See how the lungs exchange oxygen with carbon dioxide in the respiratory process.
- As you breathe, oxygen is taken in and carbon dioxide is pushed out - via the lungs.
- Air travels to the lungs through the trachea, which splits into two bronchi, each with smaller branches of bronchioles.
- The bronchioles lead to tiny air sacs, alveoli, where the exchange of oxygen and carbon dioxide occurs.
- Capillaries allow oxygen to enter the bloodstream and travel around the body.
