How many statements are correct with respect to the mechanism of breathing?
(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.

1. Two
