1. OLIVIA ARUMUGAM 8-16 Respiratory System

2. The Respiratory System Takes in oxygen Gets rid of carbon dioxide Air travels in through your mouth and into your lungs Red blood cells pick up the oxygen Red blood cells move through your body, pick up carbon dioxide, back to lungs Diaphragm pushes carbon dioxide out of your body

3. Larynx Also known as the voice box Contains the vocal chords Where the sound is made from the air breathed in and out

4. Trachea Also known as the windpipe Filters the air we breathe in Leads into the bronchi, then into the lungs

5. Bronchi One tube goes into the right lung and one goes into the left lung These tubes subdivide into bronchioles

6. Bronchioles The smallest subdivisions of the bronchi About 30 000 of them inside each lung About as thick as a strand of hair

7. Alveolus A very small air sac It is inside of the lung The air breathed in goes into these air sacs

8. Lungs Two lungs located in your chest Large and take up most of the space in your chest Enable you to breathe oxygen into your body and exhale other gases

9. Diaphragm It is a dome-shaped muscle Enables you to breathe in by moving downward Enables you to exhale by moving upward
