How does the diaphragm help in inspiration?
Asked by Topperlearning User | 14 Jun, 2016, 10:42: AM
Expert Answer
When the intra-pulmonary pressure, i.e. the pressure within the lungs, is lesser than the atmospheric pressure, the diaphragm contracts.
The contraction of the diaphragm increases the volume of the thoracic chamber, thus increasing space for more air which is withdrawn during inspiration.
Hence, the person is able to inspire.
