Expand<\/p>\n<p>The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity. During inspiration, the diaphragm contracts and flattens, which increases the volume of the chest cavity. This causes the air pressure in the chest cavity to decrease, which causes air to flow into the lungs.<\/p>\n<p>Option B is incorrect because the diaphragm contracts, not relaxes, during inspiration.<\/p>\n<p>Option C is incorrect because the diaphragm is a muscle, and muscles contract during movement.<\/p>\n<p>Option D is incorrect because the diaphragm does change during inspiration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Expand&#8221;
