Answer 1

1. Vital capacity : respiratory rate multiplied by tidal volume .Hence, option a is correct.

2. Tidal volume : amount of air normally inspired or expired. Hence option, D is correct.

3. IRV: volume of air inspired that can be normally inhaled after normal inspiration. Hence, option H is correct.

4. ERV: volume of air expired that can be normally exhaled after normal expiration. Hence, option B is correct.

5. Residual volume : volume of air that cannot be forcefully exhaled. Hence, option j is correct.

6. Total lung capacity : it is IRV+ TV+ ERV.Hence, option F is correct.

7. Respiratory rate: number of breath per minute. Hence, option G is correct.

8. Minute volume :vital capacity plus residual volume.respiratory Hence, option I. is correct

9. Spirometer: used for measuring respiratory volume. Hence, option c is correct.

10. Pulmonary ventilation : inspiration or expiration. Hence, option E is correct.

1. Pulmonary ventilation : it is the process where air flow in and flow out of the lungs. It include both inspiration and expiration .

2. Intrapulmonic pressure:it is the pressure present in the pleural cavity. It value is less than atmospheric pressure.

3. Inspiration : it is the process of breathing in oxygen inside the lungs.

4. Expiration: it is the process where carbon dioxide is expelled from the body.

Short answer questions

1. Internal respiration takes place between blood and tissue whereas external respiration takes place between lungs and blood.

2. Ractus abdominus, internal and external obliques, transverse abdominus are the muscles.
