The large flat muscle at the bottom of the chest is called the diaphragm. It plays a crucial role in respiration by contracting and expanding to facilitate breathing. When the diaphragm contracts, it creates a vacuum that allows air to flow into the lungs. It separates the thoracic cavity from the abdominal cavity.
