Muscles between the ribs contract, pulling the rib cage up and out.
The diaphragm (the muscle below the lungs) contracts and moves downward, flattening out.
These movements increase the size of the thoracic cavity, creating lower pressure (negative pressure) inside the lungs compared to the outside air.
In conditions like Multiple Sclerosis (MS), muscle weakness can impair the diaphragm and chest muscles, resulting in shallow breathing or breathing difficulties.
