Vedclass · Answer

(B) $(1)$ The volume of air involved in breathing is measured using an instrument called a $Spirometer$.$(2)$ Inspiration (breathing in) is initiated by the contraction of the diaphragm,which increases the volume of the thoracic cavity in the antero-posterior axis,thereby decreasing the intra-pulmonary pressure and allowing air to flow into the lungs.Therefore,the correct sequence is $Spirometer$ and $Contraction$.

Choose the correct option:
$(1)$ The volume of gases involved in breathing movements is measured by $Sphygmomanometer / Spirometer$.
$(2)$ Inspiration is initiated by the $relaxation / contraction$ of the diaphragm.
