The primary muscle that aids breathing in a pig is the diaphragm. This dome-shaped muscle separates the thoracic cavity from the abdominal cavity and plays a crucial role in respiration by contracting and relaxing to facilitate the inhalation and exhalation of air. When the diaphragm contracts, it moves downward, creating a vacuum that pulls air into the lungs. During exhalation, the diaphragm relaxes, pushing air out of the lungs.
