The diaphragm is located underneath the ribcage and separates the chest cavity from the abdominal cavity. It contracts and relaxes to help regulate breathing by controlling the volume of the chest cavity.
The lungs are located above the diaphragm, which is a dome-shaped muscle located at the bottom of the chest cavity. The diaphragm separates the chest cavity (where the lungs are located) from the abdominal cavity (where organs like the liver and stomach are situated). When the diaphragm contracts and moves downward, it creates more space for the lungs to expand during inhalation.
