Breathing: Lungs and Diaphragm: a 3D model for Class 7 Science, covering Breathing in: the diaphragm contracts, flattens and moves down, and the ribs move up and out, This makes the chest bigger, so the lungs expand and air flows in through the nose or mouth and windpipe, Breathing out: the diaphragm relaxes and rises, the ribs move down and in, the chest gets smaller and air flows out, Lungs have no muscles of their own; they expand and recoil because the chest around them changes size, Air travels only through the airways: throat, windpipe, bronchi and smaller tubes ending in air sacs (alveoli).
