The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is option(c) i.e, the diaphragm.

<h3>What is the diaphragm?</h3>

The diaphragm, a delicate skeletal muscle that separates the chest from the belly, is located at the base of the chest. When you breathe in, it flattens and shrinks. As a result, the lungs experience a vacuum effect that draws air in. The diaphragm relaxes and the air is forced out of the lungs when you exhale.

signs of diaphragm issues:

  • Acid reflux, heartburn, coughing, and difficulty swallowing.
  • alterations to skin tone (skin may turn blue).
  • rapid heartbeat, pressure in the chest, and/or breathing difficulties (especially when lying down).
  • Headaches.
  • Hiccups that persist or recur frequently.

Patients who need surgery for conditions affecting the chest, including diaphragm issues, are treated by a thoracic surgeon.
