- Explain to your students that the sinus cavity is the area around the nose and eyes that cleans the air people breathe in.
- Inform your students that the pharynx is behind the nose and mouth and that the larynx is in the neck and contains the vocal cords.
- Tell them that the trachea connects the pharynx and larynx to the lungs and is responsible for the passage of air, while the bronchi are small tubes that bring air to and from the lungs.
- Remind them that the lung is the main part of the respiratory system and puts oxygen into the bloodstream.
- Explain that the diaphragm is a muscle that moves up and down to expand the lungs. This helps a person breathe.
