Oxygen is needed for the Kreb's cycle to function. This releases the energy needed by the organs of the body. The brain cannot function without this energy; therefore, one will pass out before the body actually dies. Once one passes out, the lungs will expand because air will travel from high pressure to low pressure, starting the breathing.
