@teflita Inhalation: Yellow diaphragm (muscle) flattens/contracts, expanding the blue lungs (organs) down. Other red muscles, intercostals between ribs, and abdominals, also help expand the lungs down and out. This creates negative air pressure inside the lungs, causing air to flow in through the nose/mouth, pharynx, trachea, bronchi, and finally into the lungs.

@teflita Exhalation: Lungs recoil inward, drawing rib cage with them; contracted muscles return to resting state; grey viscera moves in and up. Diaphragm recoils upward, reducing volume of rib cage and creating pressure in thorax. Air is expelled from lungs, through trachea, pharynx, and nose/mouth, silently or with speech/singing.
