Question | Answer |
structure that warms, moistens, and filters air as it enters the respiratory tract; also houses the olfactory receptors for the sense of smell | nose |
| |
air-filled spaces in the skull that open into the nasal cavity | sinuses |
| |
roof of the mouth; partition between the oral and nasal cavities; divided into the hard and soft palate | palate |
| |
bony anterior (front) portion of the palate | hard palate |
| |
muscular posterior (back) portion of the palate | soft palate |
| |
throat; passageway for food to the esophagus and for air to the larynx | pharynx |
| |
part of the pharynx directly behind the nasal passages | nasopharynx |
| |
central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis | oropharynx |
| |
lower part of the pharynx, just below the oropharyngeal opening into the larynx and esophagus | laryngopharynx |
| |
oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion; also called palatine tonsils | tonsils |
| |
lymphatic tissue on the back of the pharynx behind the nose; also called pharyngeal tonsil | adenoid |
| |
small projection hanging from the back middle edge of the soft palate; named for its grape-like shape | uvula |
| |
voice box; passageway for air moving from the pharynx to the trachea; contains the vocal cords | larynx |
| |
opening between the vocal cords in the larynx | glottis |
| |
a lid-like structure that covers the larynx during swallowing to prevent food from entering the airway | epiglottis |
| |
windpipe; passageway for air from the larynx to the area of the carina, where it splits into the right and left bronchi | trachea |
| |
branched airways that lead from the trachea to the microscopic air sacs called alveoli | bronchial tree |
| |
two primary airways branching from the area of the carina into the lungs | right bronchus and left bronchus |
| |
progressively smaller tubular branches of the airways | bronchioles |
| |
thin-walled, microscopic air sacs that exchange gases | alveoli |
| |
two spongy organs in the thoracic cavity enclosed by the diaphragm and rib cage; responsible for respiration | lungs |
| |
subdivisions of the lung, with two on the left and three on the right | lobes |
| |
membranes enclosing the lung (visceral pleura) and lining the thoracic cavity (parietal pleura) | pleura |
| |
potential space between the visceral and parietal layers of the pleura | pleural cavity |
| |
muscular partition that separates the thoracic cavity from the abdominal cavity and that moves upward and downward to aid in respiration | diaphragm |
| |
partition that separates the thorax into two compartments (containing the right and left lungs) and that encloses the heart, esophagus, trachea, and thymus gland | mediastinum |
| |
thin sheets of tissue that line respiratory passages and secrete mucus, a viscid (sticky) fluid | mucous membranes |
| |
hair-like processes from the surface of epithelial cells, such as those of the bronchi, to move mucous cell secretions upward | cilia |
| |
functional tissues of any organ, such as the tissues of the bronchioles, alveoli, ducts, and sacs, that perform respiration | parenchyma |
