Diaphragm
The diaphragm muscle expands and contracts to take air into the lungs in a rhythmic and continuous action, mostly involuntarily.
The diaphragm is located in the abdomen, below the lungs, and above the digestive system. The diaphragm is responsible for breathing, vomiting, helping to pass food through the oesophagus and defecation.
