| Pharynx | passageway for food to the esophagus and air to the larynx |
| nasopharynx | part of the pharynx directly behind the nasal passages |
| oropharynx | central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis |
| laryngopharynx | lower part of the pharynx, just below the oropharyngeal opening into the larynx and esophagus |
| tonsils | oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion |
| adenoid | lymphatic tissue on the back of the pharynx behind the nose |
| uvula | small projection hanging from the back middle edge of the soft palate |

| Lobes | subdivisions of the lung, with two on the left and three on the right |
| pleura | membranes enclosing the lung (visceral pleura) and lining the thoracic cavity (parietal pleura) |
| Diaphragm | muscular partition that separates the thoracic cavity from the abdominal cavity and aids in respiration by moving up and down |
| Cilia | Hairlike projections that extend from the plasma membrane and are used for locomotion |
| parenchyma | functional tissues of any organ, such as the tissues of the bronchioles, alveoli, ducts, and sacs, that perform respiration |
