1 Created by Boundless Which of the following animals would utilize direct diffusion as a means for respiration? A Insects B All animals use direct diffusion as a means for respiration. C Cnidarians D Fish 2 Created by Boundless Which of the following statements is TRUE? A Direct diffusion is the only process used for respiration. B Cell size is a negligible factor in the process of diffusion. C The size of an animal does not play a role in the ability to diffuse and undergo gas exchange. D The more complex an organism, the more complex the respiratory system. 3 Created by Boundless Which of the following statements best describes the major function of the respiratory system? A The respiratory system allows CO2 to enter the bloodstream. B The respiratory center allows CO2 to exit the body during exhalation. C The respiratory system allows O2 to enter the bloodstream and CO2 waste to be exhaled. D The respiratory system allows O2 to enter the bloodstream. 4 Created by Boundless Which of the following statements best describes the process of gas exchange with gills as the major respiratory organ? A The gills allow the CO2 in the bloodstream to diffuse into the water. B The gills allow oxygen in water to diffuse in the bloodstream. C The gills allow oxygen in water to diffuse into the bloodstream and CO2 to diffuse into the water. D The gills do not participate in gas exchange and only transport oxygen from the water. 5 Created by Boundless Which of the following statements is TRUE regarding the process of respiration? 6 A The tracheal system uses spiracles for diffusion of O2into the body and CO2 out of the body. B The tracheal system uses trachea for diffusion of O2 into the body and CO2 out of the body. C The tracheal system does not participate in gas exchange. D The tracheal system uses spiracles to allow for entrance of O2 only into the body. Created by Boundless Which of the following is considered to be a protective mechanism utilized by the respiratory system? A presence of cilia on the bronchioles B presence of cilia on the lungs C production of mucus by the larynx D production of mucus by the bronchioles 7 Created by Boundless Which of the following represents the correct order for the movement of air into the mammalian respiratory system after it has left the nasal cavity? A pharynx, larynx, trachea, bronchus, bronchioles, alveolar duct B pharynx, larynx, trachea, bronchus, secondary bronchus, bronchioles, alveolar duct C pharynx, larynx, trachea, bronchus, secondary and tertiary bronchus, bronchioles, alveolar duct D larynx, pharynx, trachea, bronchus, secondary and tertiary bronchus, bronchioles, alveolar duct
