How many statements are correct with respect to the mechanism of breathing?
Select the correct option from the following:
1. Two
2. Three
3. Four
4. Five
| (a) | Inspiration occurs when there is a negative pressure in the lungs with respect to atmospheric pressure. |
| (b) | Lungs do not collapse between breaths and some air always remains in the lungs because there is a negative intrapleural pressure pulling at the lungs walls. |
| (c) | Expiration is initiated due to the contraction of diaphragm. |
| (d) | One can consciously breathe in and breathe out by moving the diaphragm alone, without moving the ribs at all. |
| (e) | The strength of inspiration and expiration can be increased with the help of additional muscles in the abdomen. |
