BIOL 3350 Unit 4 Review 1. What are the two parts of the respiratory system? Conducting airway (supplies the air), and the respiratory tissue (gas exchange occurs) – know where  gas exchange occurs: in the respiratory bronchioles and alveolar structures.  2. What is the function of the mucociliary blanket? It serves to clean (by trapping dust, etc.) and to moisten air that passes over it. (Defense mechanism) It doesn’t ease air movement over airways (know for test) 3. What is the purpose of the moisture in the conducting airway in relation to temperature? As the body temperature rises, more moisture is added (evaporation). 4. What is the pleural effusion? Abnormal collection of fluid in the pleural cavity. 5. What are the symptoms of influenza? List at least three. Fever, chills, general malaise  (discomfort, uneasiness)  6. What is the pleura? Is covering that protects the lungs (a double-layered serous membrane to  reduce friction of lung  movement).  Reduces friction is important 7. What is spontaneous pneumothorax? It is collapse of a portion of lung, not caused be outside influences.  Not caused be outside influence  because spontaneous. Hiking, scuba diving causes changes in air pressure 8. Define tension pneumothorax. It is caused by a side shift of the mediastinum to the opposite side (caused by an injury or other  outside influence). 9. What agent causes pneumonia? S. pneumonia (streptococcus pneumonia).  Infection that attacks the  air sacs.  Summer 2011 Page 1

10. Define hyperventilation. Higher than normal ventilation rate which will cause a  decrease in blood CO2 levels.  11. What is emphysema? Restricts oxygen absorbtion. Type of COPD. Not an obstruction caused by the formation of heline  membrane  12. What is atelectasis? Part of the lung does not expand completely. 13. What happens to the residual lung volume during an asthmatic attack? It increases, as air is trapped, and cannot contribute to vital capacity.  Symptoms of asthma: coughing  weezing shortness of breath 14. What is lung compliance? The ability for the lungs to inflate and change volume reasonable pressure.  Old balloon stretches easier  vs. new balloon 15. What is the function of the larynx? List three or more. Speech, conducts air, protects lungs from things other than air.
