1. Cell Organization
Team Work!

2. How it comes together:
The human body consists of many different types of cells that each carry out a specific function. A group of similar cells form a tissue, and the cells making up that tissue carry out the same function. Two or more types of tissues working together form an organ. Several organs that have the same function make up a system. Each system in our body has its own job. By working together, these systems make up the human body and keep us alive!

3. In other words:
Cells  Tissue  Organs  Organ Systems  Human Body

4. Cell
Definition: Smallest working unit of life that serves a specific job or function.

5. Tissue
Definition: Made of several cells similar in structure and function that work together to perform a specific job.

6. Organ
Definition- Made of similar tissues that work together to perform a specific activity

7. Organ System
Definition- Groups of one or more organs working together to perform a specific activity

8. Organism
Definition- Entire living thing that carries out all basic life functions.

9. How are Cells Specialized; Structure and their Function

10. Sperm Cell
Uses its tail, or flagellum, to swim rapidly to an egg cell during reproduction.

11. Nerve Cell
Transmits messages.

12. Muscle Cell
Stretch and contract, causing body movements

13. Red Blood Cell
Carries oxygen and carbon dioxide.

14. Cones
Cells in the eye that can detect color.

15. Brain Cells
The nerve cells in the brain transmit, receive and interpret messages.

16. Nerve Cells in the Skin
Special receptors that can detect cold and heat.

17. Rods
Cells in the eye that can detect black and white

18. Cells of the Small Intestine
Absorb nutrients.

19. Skin Cells
Form a protective body covering.

20. How does it all come together? Cells Tissue  Organs  Organ Systems

21. Body Systems Skeletal- Protects vital organs,
gives our shape, allows us
to move

22. Circulatory- carries oxygen and nutrients to the cells, waste materials are carried away, carries hormones and antibodies

23. Muscular- allow us to move,
made up of tissues that
expand and contract,
attached to bones by tendons

24. Nervous- allows the
brain to communicate
with every part of the
body, allows us to see,
hear, smell, taste
and touch

25. Respiratory- takes in oxygen, releases waste gasses

26. Immune- defense mechanism against illness

27. Digestive- converts food
into energy, packages
and transports wastes

28. Reproduction- produce egg and sperm cells and hormones, nurture developing offspring

29. Endocrine- Glands create hormones that regulate processes such as growth, reproduction and nutrients
used by body cells.
