9. The Human Body…

10. How many systems are in the Human Body?

11. BODY SYSTEMS 1. Skeletal System  bones provides internal support
protects vital tissues
and organs
allows for muscle
attachment
production of blood cells

12. BODY SYSTEMS 2. Muscular System  muscles
contract together (rarely alone)
move the bones they are anchored to
produce body heat

13. BODY SYSTEMS 3. Nervous System  neurons
the brain, spinal cord, and networks of nerves receive messages from in and outside body
nerves transmit instructions for all body activities, learning and memory

14. BODY SYSTEMS 4. Endocrine System  endocrine glands
produces hormones (chemical messengers)
hormones secrete into blood and are carried to every cell in body
hormones regulate the activity of specific tissues and organs

15. BODY SYSTEMS 5. Circulatory System  heart, blood and vessels
delivers oxygen and nutrients to all cells
removes waste from cells via blood

16. BODY SYSTEMS 6. Respiratory System  lungs
Allows for breathing to occur
exchange of gases between the inside and outside of the body
movement of gas molecules to and from the blood

17. BODY SYSTEMS 7. Integumentary System  skin, hair and nails
protects internal body
provides external support
contains sensory receptors
assists in regulating body temperature

18. BODY SYSTEMS
8. Lymphatic and Immune Systems  lymph glands and vessels, spleen, tonsils, thymus gland etc.
restores excess interstitial fluid and proteins to the blood via the subclavian veins
absorbs fats and fat-soluble vitamins from the digestive system
defends against invading organisms (eg. bacteria, viruses) by storing white blood cells in lymph nodes, spleen etc. (immune system)

19. BODY SYSTEMS 9. Digestive System
 long passageway called the alimentary canal (digestive tract)
breaks down food materials
absorbs food materials
excretes waste materials

20. BODY SYSTEMS
10. Urinary System  2 kidneys, 2 ureters, a bladder and a urethra
maintains balance of chemicals in body
removes waste products from blood as urine

21. BODY SYSTEMS 11. Reproductive System Female:
organs are situated inside body
function to ripen and release egg at regular intervals
provide protection and nourishment for fertilized egg (embryo) and fetus

22. BODY SYSTEMS Male: 11. Reproductive System
organs situated inside and outside of body
function to continuously produce sex cells (gametes) called sperm, reducing with age

23. *HINT* TASK: Your group will be given 5 particular scenarios
Work together to try to:
i) Identify the systems involved in the
scenario
ii) Describe the connections between the
body systems
*HINT*
Consider how the body
systems work together!
