Lungs do not collapse between breaths and some air always remains in the lungs which can never be expelled because?
| 1. | there is a negative pressure in the lungs |
| 2. | there is a negative intrapleural pressure pulling at the lung walls |
| 3. | there is a positive intrapleural pressure |
| 4. | pressure in the lungs is higher than the atmospheric pressure |

The figure shows a diagrammatic view of the human respiratory system with labels A, B, C, and D. Select the option that gives the correct identification, main function, and/or characteristics:
| 1. | B-pleural membrane- surrounds ribs on both sides to provide cushion against rubbing. |
| 2. | C-alveoli-thin walled vascular bag-like structures for the exchange of gases. |
| 3. | D-lower end of the lungs-diaphragm pulls it down during inspiration. |
| 4. | A trachea-long tube supported by complete cartilaginous rings for conducting inspired air. |
