| Bronchial Tree | The bronchi, the bronchioles and alveoli. |
| Bronchi | tubes that extend from the trachea and enter the lungs. |
| Bronchioles | division of the bronchi lower into the lungs. Regulate the air to the alveoli. |
| Cyanosis | A bluish color of the skin or mucous membrane caused by a low concentration of oxygen in the blood. |
| Diaphragm | chief muscle for inspiration |
| Dyspena | Difficult or labored breathing. |
| Epiglottis | located upon the larynx. A flap that closes the opening of the trachea during eating. |
| Exhalation | -process of moving air out of the lungs; the breathing out phase of ventilation. Also known as expiration. |

| Residual volume | amount of air that remains in the lungs after a forceful exhalation. |
| Respiration | movement of air in and out of the lungs: inhalation and an exhalation. |
| Surfactant | -produced in the lungs. Surfactant reduces the surface tension of fluid in the lungs and helps make the small air sacs in the lungs (alveoli) more stable. |
| Tachypena | rapid breathing. |
| Tidal Volume | amount of air moved into or out of the lungs with each breath |
| Total lung capacity | total amount of air in the lung after a maximal inhalation. |
| Trachea | windpipe Tube that extends from the larynx downward where it splits into the right and eft bronchi. |
| Tracheostomy | Performed to maintain and airway when there is an obstruction. |
| Ventilation | moving air into or out of the lungs; two phases: inhalation, exhalation |
| Vital capacity | maximum amount of air exhaled after a maximal inhalation. |
