BODY STRUCTURE

• Purpose of the Skeleton
• Muscle Function
• Tendons, Cartilage and Ligament function
• Joints

3
PURPOSE OF THE SKELETON

• Supports your body
• Protects vital organs
• Enables movement
• Blood is produced within longer bones
• Task Complete the following using these words
  Organs, Movements, Blood, Body
• Your Skeleton has four major functions, it
  supports your _______, it protects vital _______.
  _______ is produced within longer bones and it
  enables _ to occur.

4
MUSCLE FUNCTION

• Muscles work in pairs or groups
• As one muscle RELAXES and LENGTHENS the other
  CONTRACTS and SHORTENS.
• They allow joints to FLEX (bend) or EXTEND
  (straighten).
• It is important for good posture.
• Task Explain how a volleyball players leg
  muscles work to help them gain height in blocking
  the ball.

5
TENDONS, CARTILAGE AND LIGAMENT FUNCTION

• TENDONS attach MUSCLE to BONE.
• CARTILAGE, at the end of the bones acts as a
  cushion to protect.
• LIGAMENTS join BONE to BONE to provide stability.
• Task Muscles are attached to the bones by a
  connective tissue known as_______.
• ________ join bones to other bones and help
  provide stability.
• ________acts as a cushion to protect bones.

6
JOINTS

• Joints are where the bones meet.
• The Ball and Socket joint allows movement in all
  directions.
• The Hinge joint allows movement in one direction
  (open, close like a door).
• Task Explain the difference between a ball and
  socket and a hinge joint.
• Name two hinge joints and two ball and socket
  joints.

7
OXYGEN TRANSPORT SYSTEM

• This system enables you to exercise and includes
• The Respiratory System Lungs
• The Circulatory System Heart
• Both systems work together to provide muscles
  with oxygen.

8
THE RESPIRATORY SYSTEM

• Enables air to be breathed in.
• When you breathe in oxygen enters your lungs and
  is absorbed into your blood.
• Blood is pumped round your body by your heart.
• Blood carries oxygen to the working muscles.
• Task Explain how oxygen gets into the body and
  then to the working muscles.

9
THE CIRCULATORY SYSTEM

• The Heart is a muscular pump.
• As the heart beats it pumps blood round the body
  this is called your pulse rate.
• Arteries carry blood Away from the heart to the
  organs and muscles.
• Veins return blood to the heart.
• Task Describe the job of your heart.

10
THE BENEFITS OF TRAINING

• Good for Heart and Lungs.
• Increases the capacity of the Heart.
• It enables more blood to be pushed around the
  body following a contraction.
• It lowers the heart rate the lower your heart
  rate the fitter you are.
• A normal resting heart rate is between 50-80
  beats per min and during training can increase to
  around 200 bpm.
• Your recover quicker. (time it takes for heart to
  return to normal)
• Increased capacity of the lungs to take in
  oxygen
• Task Describe three benefits of regular exercise
  for your heart.

EFFECTS ON PERFORMANCE

• COURT COVERAGE
• SUPPORT DEFENCE
• SUPPORT ATTACK
• BETTER LEVEL OF SKILL AT END
• CONFIDENCE

• TASK DISCUSS THE EFFECTS OF IMPROVED HEART AND
  LUNG FUNCTION IN PERFORMING IN AN ACTIVITY OF
  YOUR CHOICE
