The diaphragm is a specialized muscle that helps in the generation of pressure gradients. Its contraction increases the thoracic volume in the:
Show answer and explanation
Correct answer: Antero-posterior axis
The contraction of the diaphragm causes it to flatten, which increases the volume of the thoracic chamber in the antero-posterior axis. This increase in volume leads to a decrease in intra-pulmonary pressure.
