| What part of the nose moistens air? | mucus |
| What part of the nose moves nasal secretions to pharynx? | mucous membrane? |
| The portions of the larynx that prevent foreign objects from entering the trachea are the | glottis and epiglottis |
| The trachea is maintained in an open position by | cartilage rings |
| The serous membrane covering the lungs is the | visceral pleura |
| The serous membrane covering the inner wall of the thoracic cavity is the | parietal pleura |
| The right lung is _____ than the left lung | larger |
| Inspiration occurs after the diaphragm _______, thus _____ the size of the thorax and _____ the pressure of the thorax. | contracts; increasing; increasing |
| Expansion of the lungs during inspiration is assisted by the surface tension of fluid in the ________ cavity. | pleural |
| The disease that results in decreased surface area of the respiratory membrane and loss of elasticity in the alveolar walls is _______. | emphysema |
| The amount of air that enters and leaves the lungs during a normal, quiet respiration is the | tidal volume |
| Air enters the nasal cavity of the respiratory system through the ______. | nostrils |
| The nasal cavity is divided by the midline _____. | nasal septum |
| The nasal cavity mucosa has several functions. Its major functions are to ______, _____, and _____ the incoming air. | warm, moisten, and cleanse |
| Mucous membrane-lined cavities called _____ are found in several bones surrounding the nasal cavities. | sinuses |
| The sinuses make the skull less heavy and probably act as resonance chambers for _____. | speech |
| The passageway is common to the digestive and respiratory systems, the ______ is often referred to as the throat; it connects the nasal cavity with the _____ below. | pharynx; larynx |
| Clusters of lymphatic tissue, _____, are part of the defensive system of the body. | tonsils |
| Reinforcement of the trachea with _____ rings prevents its collapse during _____ changes that occur during breathing. | cartilage; pressure |
| The fact that the rings are incomplete posteriorly allows a food bolus to bulge _____ during its transport to the stomach. | anteriorly |
| The larynx or voice box is built from many cartilages, but the largest is the _____ cartilage. | thyroid |

| The basic plan of the respiratory system would be similar to an inverted _____. | tree |
| the mode for gas exchange that occurs in the respiratory mechanism | diffusion |
| The upper respiratory tract includes: | nose, pharynx, larynx |
| The lower respiratory tract includes: | trachea, bronchial tree, lungs |
| lines the air distribution tubes in the respiratory tree | mucous |
| More than ____ mL of mucus produced each day forms a "mucus blanket" over much of the respiratory mucosa. | 125 |
| Mucus serves as an _______ mechanism by trapping inspired irritants such as dust, pollen | air purification |
