The fev1 as the radius of the airway was decreased

  • How well did the results compare with your prediction?
  • Air moves out of the lungs during expiration because:

Refer to Activity 1: Does the expiratory reserve volume include tidal volume? What is expiratory reserve volume?

Refer to Activity 2: Refer to Activity 3: How did the airflow change when surfactant was applied? How would you explain the effects of surfactant on airflow?

Respiratory System Mechanics Essay

Why do premature infants have trouble breathing? Refer to Activity 4: What happened to the lung in the left side of the bell jar, when the valve was opened? How did the pressure in the left lung differ from that in the right lung, after the valve was opened?

  • Refer to Activity 5;
  • There is an decrease in the volume of the lungs and increase in the intrapulmonary pressure which is greater than atmospheric pressure 10;
  • Compare the breathing rates during normal breathing, moderate exercise, and heavy exercise;
  • How would you explain the effects of surfactant on airflow?
  • IRV changed more with moderate activity 8;
  • How is it different?

Which of the following did NOT cause the left lung to deflate? How did the total airflow in this trial compare with that in the previous trial in which the pleural cavities were intact?

What would happen if the two lungs were in a single large cavity instead of separate cavities? What happened to the deflated lungs? Explain why the lungs do not inflate when the valve is closed. Why did the lung function in the deflated left lung return to normal after you clicked Reset?

Activity 3 what happened to the fev1 as the radius of the airway was decreased

Refer to Activity 5: Exploring Various Breathing patterns. What happened to the PCO2 during rapid breathing? How would you explain a decrease in PCO2during rapid breathing? What happens to PCO2 over the course of the rebreathing activity?

  • There is an decrease in the volume of the lungs and increase in the intrapulmonary pressure which is greater than atmospheric pressure 10;
  • What happened to the PCO2 during rapid breathing?
  • What happened to the PCO2 during rapid breathing?
  • IRV changed more with moderate activity 8;
  • Hypoventilation leads to retention of CO2 in the body consequently raising the blood pH;
  • Which of the following statements does not apply to the process of inspiration?

What happened to the PCO2 during breath holding? Following breath holding, what happened to the breathing pattern when normal respirations resumed? Answer choices in this exercise appear in a different order each time the page is loaded.
