The human body is a spectacular machine. It is comprised of systems and organs, tissues and bones, and a brain that helps everything function. The human body, when broken down on a much smaller scale, is made up completely of cells. In fact, the human body has between fifty and three hundred billion cells.

Inside every cell, we have mitochondria (some cells have thousands). Mitochondria, when functioning properly, produce something known as redox signaling molecules. These molecules act like little transmitters that communicate with each other. They are responsible for communicating when something goes wrong in a cell and signaling the genes to fix it.
