The internal intercostal muscles and the rectus abdominis contract during forcible exhalation. The internal intercostals pull the ribs downward and inward, reducing the volume of the thoracic cavity. The rectus abdominis contracts, pushing the diaphragm upwards and further reducing the volume of the thoracic cavity, causing air to be expelled from the lungs.
