Detailed explanation-1: -Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
Detailed explanation-2: -When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
Detailed explanation-3: -The diaphragm relaxes during natural exhalation, helping the air to pass out as the lungs deflate. Like the diaphragm, the ribs shield the lungs and expand while we inhale to promote room for the lungs to expand. Then the ribs contract, expelling the air from the lungs.
Detailed explanation-4: -The thin muscle below the lungs and heart that separates the chest from the abdomen.
Detailed explanation-5: -As the diaphragm contracts, it increases the length and diameter of the chest cavity and thus expands the lungs. The intercostal muscles and neck muscles help move the rib cage and thus assist in breathing.
