Most recreational SCUBA divers dive using an on demand regulator system. As the diver inhales, the low pressure created in the second stage regulator (the thing nearest the mouth) acts on a diaphragm inside the regulator which provides the diver with air from the tank via the first stage tank valve and a low pressure air hose.
