The diaphragm - a sheet of muscle across the rib-cage just under the lungs.
Your lungs are the largest breathing muscle in your body.

The muscle that separates the thorax and abdomen and aids in breathing is called the diaphragm. It is a dome-shaped muscle that contracts and relaxes to regulate the volume of the thoracic cavity, allowing for inhalation and exhalation.
When the smooth muscle of the bronchial tree contracts it creates a high resistance to the air flow into the lungs. Breathing is affected since the balance of oxygen and carbon monoxide is off, causing a higher respiration rate.
A muscle becomes shorter when it contracts.
