Check off all parts of the “lower” respiratory system that have each of the following structures: Structure trachea bronchi bronchioles alveoli cilia smooth muscle cartilage 2. Put these parts of the respiratory system in order during an inhalation (1 = 1 st entry of air to 7 th = last): larynx nasal cavity alveoli bonchioles bronchi trachea pharynx 3. Draw a single line on the graph to show the predicted fitness from the Heymer (breath-holding) test.

Unformatted text preview: Resistance to airflow is inversely proportional to airway size as R~ 1/(airway radius) 4 . Airflow is related to resistance as airflow ~ 1/R. From this information, draw a line on the graph to show the relative relationship between airway diameter & airflow: high Airflow low 1 2 3 4 5 6 Airway Diameter (cm) 5. Using the data from supplemental tables for this lab, plot 2 lines of the VC values for M - males & F - females who are 20 years old at the following heights: 5000 ml 4500 ml VC 4000 ml 3500 ml 30000 ml 60.6 62.2 64.6 66.1 67.7 Height in Inches for Males or Females 6. Check off ALL stimuli that cause the airways (bronchi & bronchioles) to open up or dilate: Stimulus cold air parasympathetic system sympathetic system exercise air pollution respiratory infection Dilate airways...
