Assertion (A): | It is essential for breathing that the anatomical setup of lungs in thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity. |
Reason (R): | We cannot directly alter the pulmonary volume. |
1. | Both (A) and (R) are True and (R) correctly explains (A). |
2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
Assertion (A): | An increase in pulmonary volume will cause inspiration. |
Reason (R): | An increase in pulmonary volume increases the intra-pulmonary pressure to more than the atmospheric pressure. |
