Class 11 Biology - Breathing and Exchange of Gases

Exercises

1. Define vital capacity. What is its significance?

2. State the volume of air remaining in the lungs after a normal breathing.

3. Diffusion of gases occurs in the alveolar region only and not in the other parts of respiratory system. Why?

4. What are the major transport mechanisms for CO2? Explain.

5. What will be the pO2 and pCO2 in the atmospheric air compared to those in the alveolar air?

6. Explain the process of inspiration under normal conditions.

7. How is respiration regulated?

8. What is the effect of pCO2 on oxygen transport?

9. What happens to the respiratory process in a man going up a hill?

10. What is the site of gaseous exchange in an insect?

11. Define oxygen dissociation curve. Can you suggest any reason for its sigmoidal pattern?

12. Have you heard about hypoxia?

13. Distinguish between:

(a) IRV and ERV (b) IC and EC (c) VC and TLC

14. What is Tidal volume? Find for a healthy human in an hour.
