What bodily function does the diaphragm control?

The diaphragm is a dome-shaped muscle located at the base of the thoracic cavity and plays a crucial role in respiration. During inhalation, the diaphragm contracts and flattens, creating a vacuum effect that pulls air into the lungs. This process allows for gas exchange to occur, as oxygen is taken in and carbon dioxide is expelled during exhalation when the diaphragm relaxes and returns to its original shape.

Understanding the diaphragm's function is essential, as it is a primary muscle involved in the breathing process, distinguishing it from other bodily functions such as circulation, digestion, and reproduction, which are governed by different systems and processes in the body.
