What is the function of the diaphragm in the human respiratory system?

The diaphragm is a dome-shaped muscle located at the base of the lungs. It plays a crucial role in respiration by contracting and flattening during inhalation, which increases the thoracic cavity’s volume and decreases the pressure inside, allowing air to flow into the lungs. During exhalation, the diaphragm relaxes and returns to its dome shape, reducing the thoracic cavity’s volume and increasing pressure, pushing air out of the lungs.
