The Human Body Part 1: Skeleton-Muscular System

1. Siemens Education The Human Body Part 1: Skeleton-Muscular System

2. The Human Body • Overall learning objectives • To understand the functions of the skeleton • To be able to explain various features of the skeleton • To relate images of bones, muscles and joints to diagrams and the body

3. The Human Body • Learning Outcomes: • Clear identifications of key features of the skeleton • Explanation of form and function of parts of the skeleton

4. The Human Body • Skeletons • Do you have a skeleton? • How do you know?

5. The Human Body • What makes your arm move? • If you use the animation on the Siemens interactive you can see how the muscles in your upper arm make your lower arm move. • Try it with your own arm – can you feel the muscles working?

6. The Human Body • What other animals have skeletons?

7. The Human Body • Not all animals have skeletons. • Can you name some that don’t?

8. The Human Body • Why do we have a skeleton?

9. The Human Body • Imagine if we didn’t have bones • What would our limbs feel like? • Could we move and, if so, how? • Could we stand? • Would our muscles still function? • How do animals that don’t have bones function (e.g. octopus, snail, spider)

10. The Human Body • What are the names of the bones in the body?

11. The Human Body • What if we walked on ‘all fours’? • Would that make us more or less stable? • What is it about our arms that might make us more stable? • Why don’t we walk on ‘all fours’?

12. The Human Body How do these packets protect their contents? • Protection

13. The Human Body • How can a skeleton of rigid bones move? • Construct a model arm to see how bone and muscle work • How well does cardboard represent bone? • How well elastic represent muscle? • How well does the paper fastener represent a joint?

14. Siemens Education The Human Body Part 2: The Digestive System

15. The Human Body • Overall learning objectives: • Identify parts of the digestive system • Describe their function • Overall learning outcomes: • Describe what happens to food as it goes through the body

16. The Human Body Draw and annotate what you think happens to food when you eat it

17. The Human Body

18. Siemens Education The Human Body Part 3: The Circulatory System

19. The Human Body • Overall learning objectives: • To describe how the circulatory system works • To describe to purpose of the main parts of the circulatory system • Overall learning outcomes: • To be able to explain what the circulatory system does and how

20. The Human Body • Which parts of the body does the blood system include? • What does blood do? • What else do you know about the blood system?

21. The Human Body Where is the heart? • Body diagram

22. The Human Body The pulse is the heart beating, pumping blood around the body Work in pairs to think about answers to: There are many places where blood vessels can be seen, such as on the palm of the hand. Why can no pulse be felt there? When you’re feeling your pulse, you should use your finger tips and not your thumb. Why? Why is the heart pumping blood around your body?

23. The Human Body Trace around with your finger, showing how blood is pumped to the lungs where oxygen is collected and carbon dioxide released, and then returns to the heart. It then goes to other parts of the body, carrying oxygen and nutrients, and collecting carbon dioxide and waste.

24. The Human Body Blood flows from arteries (at high pressure), through capillaries (very narrow) and back via the veins (lower pressure) to the heart again. Capillaries are where the transfers take place.

25. The Human Body Think about your ideas bout blood and the circulatory system. Did you have any ideas that you now think were not correct? Do you have any new ideas?
