Detailed explanation-1: -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 should be viewed as two distinct muscles, crural and costal, which act in synchrony throughout respiration. However, the activities of these two muscular regions can diverge during certain events such as swallowing and emesis.
Detailed explanation-3: -Your heart, lungs, and the upper part of your esophagus (food pipe) are in the thoracic cavity above the diaphragm. Your lower esophagus, stomach, intestines, liver, and kidneys are below the diaphragm, in your abdominal cavity.
Detailed explanation-4: -(DY-uh-fram) The thin muscle below the lungs and heart that separates the chest from the abdomen.
