3. Cell: the smallest unit of life that isconsidered a living thing
4. Tissue: a group of cells that worktogether and perform a function.
5. Organ: a group of similar tissues thatwork together to perform a function.
Some human organs are: heart,lungs, brain, stomach, andmuscles.
6. Organ System: one or more organs thatwork together and perform one or morefunctions.
Some human organ systems are: skeletal system, muscular system,nervous system, cardiovascular system, digestive system, and therespiratory system
7. Organism: the most complex living thing.Organisms contain many organ systems that each have theirown function, but depend on each other to help theorganism function.
-All levels of organization need to function in order for theorganism to be alive and healthy.
- If one level of the levels of organization fails, theorganism would not function properly and would die.
