Like a microscopic workforce of a million particles, your cells come in a variety of sizes and each has a unique function.
Start by taking a deep breath and exhaling. Through your lungs the oxygen particles have been absorbed and transferred to blood cells, which carry the oxygen to every part of your body that needs it, including major organs, the brain, muscle tissue and nerves. And that breath is just one of hundreds of thousands of similar functions or exchanges that happen at the cellular level each day, to keep you thinking, moving, eating, digesting and in good health.
Just as your cells are able to carry oxygen and other materials to your body through your blood stream, they are also susceptible to carrying negative elements, such as oxidants that attach to healthy cells and impede their functioning.
