One of the most amazing things about the human body is the incredible range of movement and mobility it has. This day to day activity is accomplished by our muscles through the extraordinary and facinating ability of converting chemical energy, energy stored in nutrients, into mechanical energy, energy of movement. Muscles are often viewd as the "machines" of the body. They help move food from one organ to another, and carry out our physical movement. There are three diffrent kinds of muscles in our body: cardiac, smooth, skeletal.
