The diaphragm is the muscular sheet that separates the abdomen from the chest cavity..
The diaphragm is a thin sheet of muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.
