Antero-posterior axis

Vedclass · Answer

(B) The process of breathing involves two stages: inspiration and expiration. During inspiration,the diaphragm contracts,which flattens its dome-shaped structure. This contraction increases the volume of the thoracic cavity in the $Antero-posterior$ axis. Simultaneously,the contraction of external intercostal muscles lifts the ribs and the sternum,causing an increase in the volume of the thoracic cavity in the $Dorso-ventral$ axis. Therefore,the contraction of the diaphragm specifically increases the thoracic volume along the $Antero-posterior$ axis.

The contraction of the diaphragm increases the volume of the thoracic cavity in which axis?
