1. The main purpose of the conducting airways is to provide a passageway between ambient (atmospheric) air and the gas exchange membrane of the lung (the aveoli), it only provides a passageway where air can reach the aveoli it has nothing to do with gas exchange.

2. The upper airway is composed of the nose, epithelium, 3 paired cartilages, the pharynx, paranasal sinuses, intrinsic muscles, the larynx, and the oral cavity. 3. The functions of the nose include to filter, warm, and humidify.

4. A new born is the most common patient seen with nasal flaring because infants want to use their mouth to suck causing respiratory distress and an overuse of breathing through the nasal causing nasal flaring.

5. The stratified squamous epithelium is made up of several cells and is found in the nasal cavity, the oral cavity, the oropharynx, and the laryngopharynx it is also nonciliated.

30. The purpose of the cilia is to move mucus toward the larynx the process: the cilia move in wave like fashions through the sol layer and continually strike the innermost portion of the gel layer (1500 times per minute) which propels the mucus layer with any foreign particles stuck to the gel layer toward the larynx at 2 cm per minute the cause of the cilia movement is unknown from the larynx the cough mechanism moves secretions farther up into the oropharynx

31. Conditions that can slow down the mucociliary transport system include excessive bronchial secretions associated with chronic bronchitis, emphysema, bronchiectasis, and cystic fibrosis also smoking, dehydration, positive pressure ventilation, endotracheal suctioning, high inspired oxygen concentration, hypoxia, occupational dusts, irritating chemical vapors, indoor air pollution, outdoor air pollution, general anesthetic, and parasympatholytic drugs can all cause irritation or inflammation.
