Vedclass · Answer

(D) Forced breathing or forced expiration is an active process that requires the contraction of additional muscles beyond those used in quiet breathing.$1$. The $Diaphragm$ and $External Intercostal$ muscles are primarily involved in normal inspiration.$2$. During forced expiration,the $Abdominal$ muscles contract to push the diaphragm upward,and the $Internal Intercostal$ muscles pull the rib cage downward.$3$. During forced inspiration,accessory muscles in the $Neck$ (such as the $Sternocleidomastoid$ and $Scalene$ muscles) help to further elevate the rib cage.Therefore,all the mentioned muscle groups are involved in forced breathing processes.
