Vedclass · Answer

(D) $1$. Inspiration is an active process that occurs due to the contraction of muscles.$2$. The diaphragm and external intercostal muscles contract simultaneously during inspiration.$3$. This contraction increases the volume of the thoracic cavity in the antero-posterior and dorso-ventral axes, leading to a decrease in intrapulmonary pressure, which allows air to flow into the lungs.$4$. Since the assertion states that inspiration occurs due to muscular relaxation, it is incorrect.$5$. The reason correctly states that the diaphragm and external intercostal muscles contract during inspiration.$6$. Therefore, the assertion is incorrect, but the reason is correct.

Assertion: Inspiration occurs due to muscular relaxation.
Reason: During inspiration, the diaphragm and external intercostal muscles contract simultaneously.
