There are many kinds of cells in the human body, each doing their own important job. The smallest units of the body – the cells – are individually too small to be seen by the naked eye. Yet when many like cells are together, they form a tissue. Two or more kinds of tissues together form each of our organs, like the heart or lungs. Many organs together form an organ system, like your digestive system or your respiratory system. All the organ systems together form an organism, like you or your dog or a blue whale.
The body's organization goes from cells to tissues to organs to organ systems to a whole working organism.
Look at the Chart below to see how each kind of cell in the body builds into an essential organ system. Then follow them below for a more detailed look at each.
