                               How are cells organized to build the human body?

❶ Cells to tissues

                                 Muscle Cell

   • There are many shapes and sizes of cells, because cells must be
   specialized to perform specific function.

➢ They are in the form of long fibers to allow movement.
➢ They must be able to store and use energy quickly.
➢ They do not work alone, because the size of the muscle cell is very small.
➢ They are bundled (collected) together to form tissues

     ❷ Tissue to organ

➢ Bundles of tissues are organized to form the muscle.
➢ The muscle is considered an organ
➢ Example: The muscle that lies on the front part of upper arm between

     the elbow and the shoulder.
