Detailed explanation-1: -The diaphragm is the main muscle for breathing. This dome-shaped wall of muscle does most of the breathing work by expanding and contracting the chest to draw air in and out of your lungs. When the diaphragm contracts, air is pulled into your airway through your nose or mouth.
Detailed explanation-2: -Your lungs bring fresh oxygen into your body. They remove the carbon dioxide and other waste gases that your body’s doesn’t need. To breathe in (inhale), you use the muscles of your rib cage – especially the major muscle, the diaphragm.
Detailed explanation-3: -Signals from the respiratory centre in your brain travel down nerves to your diaphragm and other muscles. The diaphragm is pulled flat, pushing out the lower ribcage and abdomen. At the same time, the muscles between your ribs pull your rib cage up and out. This expands the chest and draws air into the lungs.
