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.
