What are the Functions of the Diaphragm?
If you’re wondering as to what is the main function of the diaphragm, then it is to help in breathing. When a person inhales, the diaphragm contracts and thus, enlarges the space available in the thoracic cavity. The external intercostal muscles also help bring about this enlargement of the thoracic cavity. This enlargement thus creates a negative pressure which leads to a suction force and drawing of air into the lungs. After inhalation, when the diaphragm relaxes, air is exhaled due to the elastic recoil of the lungs and the tissues lining the thoracic cavity. The abdominal muscles also help in this, by acting as antagonists to the effects of diaphragm. There is a specific type of breathing which is known as diaphragmatic breathing or abdominal breathing. This is the act of breathing deep into the lungs by flexing the diaphragm. This is the opposite of breathing in a shallow manner, which is done when flexing one’s rib cage. This deep breathing leads to expansion of the stomach rathe
