Explanation:
Detailed explanation-1: -Overview. The diaphragm, located below the lungs, is the major muscle of respiration . It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.
Detailed explanation-2: -The diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for breathing in (called inhalation or inspiration). The diaphragm is attached to the base of the sternum, the lower parts of the rib cage, and the spine.
Detailed explanation-3: -The diaphragm has ONLY skeletal muscle, not smooth muscle-none.
