1. Body Organization and Structure

2. DO AN ICE JOB!
1. What initially happens when the ice touches your skin?
2. What happens after more time passes?
3. What happens when the ice is removed?
4. How do you think Jack Thayer managed to survive after the sinking of the Titanic?

3. HOMEOSTASIS My Beloved Cells I will miss you!
If homeostasis is interrupted, cells suffer and sometimes die.
The human body’s maintenance of a stable internal environment.
My Beloved Cells
I will miss you!

4. THE WORK OF CELLS
On a baseball team, every player has his job.
Cells have their own positions (or jobs) in the body!

5. RED BLOOD CELLS

6. Groups of cells working together form a TISSUE
There are 4 types of tissues:
Epithelial Tissue
Nervous Tissue
Muscle Tissue
Connective Tissue

7. EPITHELIAL TISSUE
Covers and protects underlying tissue. When you look at the surface of your skin, you see epithelial tissue

8. NERVOUS TISSUE
Sends electrical signals through the body. It is found in the brain, nerves and sense organs.

9. MUSCLE TISSUE
Made up of cells that can contract and relax to produce movement

10. CONNECTIVE TISSUE
Joins, supports, protects, insulates, nourishes, and cushions organs. It also keeps organs from falling apart.

11. TISSUE + TISSUE= ORGAN
Two or more tissues working together, form an organ.
One type of tissue alone cannot do all of the things that several types working together can do.

12. ORGAN + ORGAN = ORGAN SYSTEM
Organs working together
make up an organ system.
The failure of any part can affect the entire system

13. 11 MAJOR ORGAN SYSTEMS Integumentary system Muscular system
Skeletal system
Cardiovascular system
Respiratory system
Urinary system
Reproductive system.
Nervous system
Lymphatic system
Digestive system
Endocrine system

14. Integumentary System
Includes skin, hair, nails and their underlying tissues

15. Skeletal muscles move bones.
Muscular System
Skeletal muscles move bones.

16. Skeletal System
Bones frame and protect body parts.

17. Cardiovascular System
The heart pumps blood through blood vessels.

18. Respiratory System
Lungs absorb oxygen and release carbon dioxide.

19. Removes wastes from the blood and regulates body fluids.
Urinary System
Removes wastes from the blood and regulates body fluids.

20. Reproductive System
Females produces eggs, feed/shelter unborn baby- males produce sperm.

21. Receives and sends electrical messages.
Nervous System
Receives and sends electrical messages.

22. Lymphatic System
Returns leaked fluids to blood vessels and helps flush harmful germs out.

23. Digestive System
Breaks down food into nutrients.

24. Endocrine System
Glands regulate body functions by sending out chemical messages.

26. DISCUSSION QUESTIONS
1. Explain the relationship between cells, tissues, organs and organ systems.
2. Compare the four kinds of tissues found in the human body.
3. Describe a time when homeostasis was disrupted in your body.
Which body systems do
you think were effected?

27. T/F QUICK QUIZ
Homeostasis is the maintenance of a stable internal environment.
Epithelial tissue sends electrical signals throughout the body.
Blood is a type of connective tissue.
The endocrine system consists of skin, hair, nails and their underlying
tissue.
5. The lymphatic system returns
leaked fluids to blood vessels.
