1. Which of the following is not a function of the respiratory system? A) provide an area for gas exchange between air and circulating blood B) transport air to and from the cells and tissues through... out the body C) condition gases before they reach the exchange surfaces of the lungs D) defend respiratory system and other tissues against inhaled bacteria 2. Which selection includes only upper respiratory tract components? A) nose, mouth, pharynx, and larynx B) larynx, trachea, bronchi, and lungs C) bronchi, respiratory bronchioles, and alveoli D) nose, nasal cavity, paranasal sinuses, and pharynx 3. The lower respiratory tract extends from the to the , inclusive. A) larynx; alveoli B) pharynx; lungs C) trachea; alveoli D) pharynx; alveolar sacs 4. The functional division of the respiratory system that transports air (as opposed to exchanging gases with the blood) is called the A) upper respiratory tract B) lower respiratory tract C) respiratory portion D) conducting portion 5. Air filtration and conditioning, olfaction, and sound resonance are all functions of the A) oral cavity B) nasal cavity C) pharynx D) larynx 6. Goblet cells are found throughout the conduction zone of the respiratory tract. These cells produce in order to protect the membranes in which they are found. A) white blood cells B) mucus C) type II alveolar cells D) type I alveolar cells 7. These cells found in the alveolar wall allow for rapid diffusion of gases across the cell membranes. A) white blood cells B) goblet cells C) type II alveolar cells D) type I alveolar cells 8. These cells found in the alveolar wall produce surfactant which reduce the collapse of alveoli. A) white blood cells B) goblet cells C) type II alveolar cells D) type I alveolar cells 9. Regions of the pharynx include which of the following? A) nasopharynx B) oropharynx C) laryngopharynx D) all of the above 10. Which selection correctly pairs a pharyngeal region with its lining? A) nasopharynx; nonkeratinized stratified squamous epithelium B) oropharynx; nonkeratinized stratified squamous epithelium C) laryngopharynx; pseudostratified ciliated columnar epithelium D) none of the above 11. A tough, flexible tube that connects the larynx to the bronchi of the lungs is called the . It is surrounded by 15 to 20 C-shaped rings of hyaline cartilage. The purpose of these rings is to keep the tube (means open and unobstructed). A) pharynx, patent B) laryngopharynx, flexible C) larynx, flexible D) trachea, patent 12. Cartilages of the larynx include all of the following except the A) arytenoid cartilages and epiglottis B) lateral cartilages and alar cartilages C) thyroid cartilage and cricoid cartilage D) corniculate and cuneiform cartilages 13. The spoon-shaped , composed mostly of elastic cartilage, closes over the laryngeal opening when a person swallows. A) epiglottis [Show More]
