  • Questions and answers regarding size and location. Use white board to draw size, location and then a diagram of layer.
  • Images of each layer.
  • Why is the heart split into left and right sections? What is meant by “oxygenated” and “deoxygenated”? Which colour is which? Why are the ventricles larger?
  • What is meant by inferior and superior vena cava?
  • What are the valves made up of? What is their link with the associated noise of a heart beat? What are “semi – lunar” valves?
  • Listen for the “lup dup” noise Pause video and ask group to name valves before they are shown.
  • Final version of heart fully labelled. Go through each again, then let group label their own diagrams in their handbook. Make sure PowerPoint is blank when they detail their diagrams.
  • With what we have labelled in our books, how can you describe the above process? Put into active learning phase using tables to for heart, lungs and body tissues. Students can be blood transporting around the body.
  • What happens in the lungs? What is Systemic Circulation? What is Pulmonary Circulation?
  • Heart is muscle and thus needs oxygenated blood for fuel and energy. Coronary arteries feed the heart this. Explain how blockages effect and cause heart disease.
  • Put group into teams of 4. For each question the groups must give the letter that they think is correct. Using whiteboard, draw scores and keep tabs.
  • The heart

    1. 1. The Heart Lloyd Dean NVQ Level 3 Personal Training
    2. 2. Aims of Lesson <ul><li>By the end of the lesson you should be able to: </li></ul><ul><li>Describe the structure of the Heart </li></ul><ul><li>Explain the flow of blood through the Heart </li></ul><ul><li>Label the heart </li></ul>
    3. 3. The Heart Structure <ul><li>Size and Location </li></ul><ul><li>3 Layers of Heart Wall </li></ul><ul><li>Pericardium (Outer Layer) </li></ul><ul><li>Reduce friction & maintain heart shape </li></ul><ul><li>Myocardium (Middle Layer) </li></ul><ul><li>Largest layer and used in electrical impulse of heart beat </li></ul><ul><li>Endocardium (Inner Layer) </li></ul><ul><li>Prevent friction between flowing blood and heart muscle </li></ul>
    4. 4. The Heart Structure “ Cardium” – Heart “ Peri” – On, around “ Myo” – Muscle “ Endo” – Within, Inward
    5. 5. Heart Chambers <ul><ul><ul><li>RIGHT ATRIUM </li></ul></ul></ul><ul><ul><ul><li>LEFT ATRIUM </li></ul></ul></ul><ul><ul><ul><li>RIGHT VENTRICLE </li></ul></ul></ul><ul><ul><ul><li>LEFT VENTRICLE </li></ul></ul></ul><ul><ul><ul><li>MUSCLE </li></ul></ul></ul>
    6. 6. <ul><ul><ul><li>Septum – Divides the two sides of the heart preventing oxygenated blood mixing with deoxygenated blood. </li></ul></ul></ul><ul><ul><ul><li>Pulmonary Vein – Transports oxygenated blood to the heart. </li></ul></ul></ul><ul><ul><ul><li>Aorta – Transports oxygenated blood away from the heart to the body. </li></ul></ul></ul><ul><ul><ul><li>Vena Cava – Transports deoxygenated blood from the body back to the heart. </li></ul></ul></ul><ul><ul><ul><li>Pulmonary Artery – Transports deoxygenated blood to the lungs. </li></ul></ul></ul>AORTA PULMONARY VEIN PULMONARY ARTERY VENA CAVA SEPTUM
    7. 7. Valves in The Heart <ul><li>4 Valves in the heart </li></ul><ul><li>Bicuspid Valve - Found between the left ventricle and the left atrium and prevents backflow of blood from the left ventricle to the left atrium. Also known as Mitrial valve. </li></ul><ul><li>Tricuspid Valve - Found between the right ventricle and the right atrium and prevents backflow of blood from the right ventricle to the right atrium </li></ul><ul><li>Aortic Valve - Found in the aorta. They prevent backflow of blood into the left ventricle. </li></ul><ul><li>Pulmonary Valve – Found in the pulmonary artery and prevents backflow of blood into the right ventricle. </li></ul><ul><li>How do the valves make sure that blood does not flow backwards? </li></ul><ul><li>Chordae Tendinae </li></ul>
    8. 8. The Valves Working
    9. 9. The Heart
    10. 10. Blood Flow Through Heart
    11. 11. Circulation of Blood <ul><li>Video….ensure “developer” is enabled at the top of the powerpoint via powerpoint options. </li></ul>
    12. 12. The Heart Structure and Function <ul><li>How does the heart receive energy? </li></ul><ul><li>With the person sat next to you describe and draw how blood flows through the heart </li></ul><ul><li>The heart beats between 80,000 to 100,000 times and pumps approximately 23,000 litres of blood a day </li></ul><ul><li>That means it will have beat 2-3 billion times and pumped 50-65 million gallons of blood over a 70-90 year lifespan </li></ul><ul><li>Remember to look after it! </li></ul>
    13. 13. Aims of Lesson <ul><li>You should know be able to: </li></ul><ul><li>Describe the structure of the Heart </li></ul><ul><li>Explain the flow of blood through the Heart </li></ul><ul><li>Label the heart </li></ul>
