Understanding the Skeleton and Joints: Key Functions for Standard Grade PE

This lesson focuses on the key components of the human skeleton and its functions in physical education. Students will explore the three main functions of the skeleton, including support, movement, and protection. Additionally, the structure and function of synovial joints will be covered, highlighting the two main types. An understanding of the circulatory system will also be introduced as part of the body's overall functionality in physical activity. Success will be measured by the ability to articulate these concepts clearly.

  1. Standard Grade PE

    The Body
  2. Learning Outcomes The function of the skeleton Joints – structure and function The circulatory system SUCCESS CRITERIA To be able to describe the 3 main functions of the skeleton To name and describe the 2 types of synovial joints To be able to explain the process of circulation.
  3. The purpose of your skeleton Your skeleton has three main functions. It supports your body It protects vital organs 3. Lastly it enables movement
  4. JOINTS
  5. JOINTS Joints which allow free movement are called SYNOVIAL JOINTS – they are either HINGE joints (e.g. the knee) or BALL AND SOCKET (e.g. the hip)
  6. Synovial Joints Bone Cartilage Synovial fluid Joint capsule
  7. Synovial joints Ball and socket joints – can move in all directions – which joints in the body would be ball and socket? Hinge joints open and shut – which joints in the body would be hinge joints?
  8. Protecting Joints Synovial fluid – acts as a lubricant Cartilage – covers the end of the bones and reduces friction between the bones Muscles – create movement and help hold the joint stable Ligaments – hold the connecting bones together Tendons – attach muscle to bone. They help create the muscle movement
  9. Cardio-Respiratory system http://www.youtube.com/watch?v=cbNWI2WsWFg
  10. OXYGEN TRANSPORT SYSTEM In order to work and create movement, muscles need oxygen. The body's oxygen transport system takes oxygen to the working muscles, through the circulatory and respiratory systems working together. The main workers are the heart, blood and lungs. The whole oxygen transport system works in a cycle.
  11. Design a poster….. Design a poster describing the circulatory system, using the next slide to help you…! Who can design the best one!!!
  12. The Respiratory System Oxygen enters the body through the AND Nose Mouth The oxygen then travel to the lungs where the oxygen enters the bloodstream The oxygen then travel in the arteries to the which pumps the oxygen to the working muscles HEART
  13. Cardio-respiratory system – Benefits of a good CR system: Heart rate Time
  14. Benefits of a good Cardio-Respiratory System Allows you to maintain a high standard of performance for a long time Less effort required for the same amount of work You can recover quicker IMPROVES WITH TRAINING!!! WHY?
