| we get the oxygen that the human body needs | when we breath |
| is a waste product of breathing | carbon dioxide |
| is the responsible for respiration | The Respiratory System |
| Oxygen and Carbon Dioxide | are gases that are in the air |
| The lungs fill with air | when we inhale |
| passageway common to the digestive & respiratory systems; the throat | pharynx |
| The oxygen is exchanged for carbon dioxide | In the alveoli |
| air leaves the lungs | when we exhale |
| contains a lot of carbon dioxide | The air that lives the lungs |
| voice box | larynx |
| period of breathing when air enters the lungs | inspiration |
| period of breathing when air exits the lungs | expiration |
| causes an increased use of the inspiratory and expiratory reserve volumes | exercise |
| thorax & lung volume during diaphragm contraction | increases |
| thorax pressure during diaphragm contraction | decreases |
| direction of air flow during diaphragm contraction | in |
| direction of rib movement during diaphragm contraction | out |
