What is the large of muscle that controls the size of the chest cavity?

Answer 1

The large muscle below the lungs that make them expand and bring in air is called the diaphragm. (dye-uh-fram). During inhalation, the diaphragm contracts, thus enlarging the thoracic cavity (the external intercostal muscles also participate in this enlargement). This reduces intra-thoracic pressure: In other words, enlarging the cavity creates suction that draws air into the lungs. When the diaphragm relaxes, air is exhaled by elastic recoil of the lung and the tissues lining the thoracic cavity in conjunction with the abdominal muscles, which act as an antagonist paired with the diaphragm's contraction.

During exercise or stress or any other cause of labored breathing, air movement is assisted by scalenes, sternocleidomastoid, intercostal muscles, serratus posterior (inferior and superior), all the abdominal muscles, and maybe levator costorum (we still dont know their exact function).
the diaphragm, the internal and external intercostal muscles and other accessory muscles such as sternocleidomastoid and others.
