Diaphragm position: When you inhale your diaphragm contracts descending lower in the chest. The opposite is true for exhaling. Other chest muscles are involved in respiration such as the intercostal (internal and external fibers), scalene and sternocleidomastoid muscles. Abdominal muscles also contribute to forceful exhalation.
