| Question | Answer |
|---|---|
| Small air sacs in the lungs where oxygen and carbon dioxide are exchanged. | alveoli |
| Wind pipe | trachea |
| Site of bifurcation (The Split) to the mainstem bronchi in the lungs | carina |
| The voice box | larynx |
| The throat; contains the passageways for food and for inhaled and exhaled air. | pharynx |
| Large divisions of the lung, visible on the outer surface | lobes |
| Small hairs that flow in waves to move foreign particles away from the lungs | cilia |
| Covers the outer surface of the lungs and lines the inner surface of the rib cage. | pleura |
| Muscular sheet that divides the thoracic cavity from the abdominal cavity. Most important ventilation muscle. | diaphragm |
| Tubular air passages that branch off the trachea to the right and left and enter each lung. They carry inhaled and exhaled air to and from the lungs. | bronchi |
| Small tubular air passageways that branch off the bronchi. They carry inhaled and exhaled air to and from the alveoli. | bronchioles |
| The paired external openings of the nasal cavity. | nares |
| Lid-like structure that seals off the larynx, so that swallowed food goes into the esophagus. | epiglottis |
| The bulk movement of gas into and out of the lungs. | ventilation |
| The process of gas exchange at the lungs or tissue sites. Oxygen and carbon dioxide are exchanged in the alveoli during external respiration. Oxygen and carbon dioxide are exchanged at the cellular level during internal respiration. | respiration |
