Question

Quizplus · Accepted Answer

The diaphragm is a muscle that plays a crucial role in breathing by contracting and relaxing to help expand and decrease the volume of the thoracic cavity. However, it is not a respiratory organ as it does not participate in gas exchange with the environment. The other options, larynx, bronchi, and nose, are all respiratory organs involved in breathing and gas exchange.
