Vedclass · Answer

(D) The process of inspiration (breathing in) follows a specific physiological sequence:$1$. $III$ - Contraction of the diaphragm and external intercostal muscles (respiratory muscles) occurs first.$2$. $IV$ - This contraction leads to an increase in the thoracic volume.$3$. $I$ - The increase in thoracic volume causes a corresponding increase in lung volume.$4$. $II$ - According to Boyle's Law,an increase in volume leads to a decrease in intrapulmonary pressure compared to atmospheric pressure.$5$. $V$ - Consequently,air rushes into the lungs from the outside to equalize the pressure.Therefore,the correct sequence is $III \rightarrow IV \rightarrow I \rightarrow II \rightarrow V$.

State the sequence of events for inspiration (breathing in).
$I$ - Increase in lung volume
$II$ - Decrease in intrapulmonary pressure
$III$ - Contraction of respiratory muscles
$IV$ - Increase in thoracic volume
$V$ - Air rushes into the lungs
