Vedclass · Answer

(B) Expiration in mammals,including rabbits,is a passive process during quiet breathing. It occurs primarily due to the relaxation of the diaphragm muscles (which return to their dome-shaped position) and the external intercostal muscles. However,during forced expiration,the internal intercostal muscles contract to pull the rib cage downward and inward,further decreasing the thoracic volume and increasing thoracic pressure to expel air.
