The diaphragm consists of skeletal muscle separating the thoracic cavity and the abdominal cavity. During inhalation the diaphragm contracts, while it is convex during exhalation.
Your abdominal muscles are important because they act as the muscles of exhalation. The abdominal muscles work together with the inhalation muscles to send strong and smooth airflow to the vocal
