GCSE PE Lesson 6: Cardiovascular system 02/05/2017 Starter Use the sugar paper on your table to record what you have learned about the cardiovascular system After 2 minutes move clockwise around the room and add, build or challenge other groups’ learning Checklist: Components of the CV system Structure of the heart Pathway of the blood Extension Prioritise your learning for today What do you need to learn? 2 minutes Learning Challenges ➔ Remember the components of the cardiovascular system ➔ Understand how the heart works as a double pump to transport blood around the body ➔ Apply your understanding of the respiratory and cardiovascular system to explain how the cardio-respiratory system supports exercise Activity 1: Cardiovascular system a. Work with a partner or teacher to validate your home learning worksheets b. Construct a model or draw an annotated diagram to show the blood’s pathway around the CV system c. Use an association strategy to help you remember the blood’s pathway around the CV system d. Prepare a lesson to teach the blood’s pathway around the CV system to your peers Why is the heart called a double pump? 15 minutes Extension Challenge yourself and try to complete more than one activity to deepen your understanding Activity 2: Cardio-respiratory system Practical activity: Participate in a short bout of vigorous activity What do you notice about the changes in your breathing and heart rate? Why has this happened? How do the cardiovascular and respiratory systems work together to support exercise? 5 minutes Key terms Deoxygenated blood Blood containing a low concentration of oxygen Oxygenated blood Blood containing a high concentration of oxygen Heart rate The number of times your heart beats in one minute. One heart beat is one contraction and one relaxation of the heart. Heart rate is measured in beats per minute (bpm). Pulse The rhythmic throbbing that you can feel as your arteries pump blood around the body. You can measure your heartrate using your pulse. Backflow The flowing backwards of blood. Valves in the veins prevent backflow. 5 minutes Plenary Create a revision question card based on today’s learning Home Learning ● Sixth person in the register adds the key terms to the Moodle glossary ● Read pages 22-23 of the textbook Complete worksheets 1.15 and 1.16
