| Banned | Flexing of the diaphragm causes the lungs to contract or enlarge due to pressure. According to gas laws, when you lungs contract, the pressure increases which causes the air to be forced out of your lungs (exhale omg). When your lungs expand the pressure decreases to below that of the room around you, which in turn, causes air to rush back into the lungs. Rinse, repeat, ect ect... |
