Title: Review Sheet Exercise 37B Respiratory System Mechanics Post by: kmuhs on Nov 30, 2011 I need a little help
3. What does the pump rate stimulate? 4. How did changing the radius effect FEV1 (%)? 7. What effect does the addition of surfactant have on airflow? 8. Why does surfactant affect airflow? Title: Re: Review Sheet Exercise 37B Respiratory System Mechanics Post by: bio_man on Nov 30, 2011 4. How did changing the radius effect FEV1 (%)? Decreasing radius caused a decrease in FEV1 (%) What does the pump rate stimulate? Respiratory rate Please remember that it's two questions per topic.

It stimulates respiratory rate. 7. What effect does the addition of surfactant have on the airflow? It causes increased airflow 8. Why does surfactant affect airflow? It causes reduced surface tension in the alveoli, so the alveoli can expand more. |
