Explain that: The heart pushes blood through arteries to all parts of the body. Blood returns to the heart through the veins. The lungs infuse the blood with oxygen from the air and get rid of waste. The blood carries oxygen and food through the arteries to keep the body healthy and strong. The blood also carries waste away from the body. All the parts the heart, lungs, blood, arteries and veins work together as part of the circulatory system.

The Powerful Heart The Heart and The Circulatory System Review and summary Review the key messages of the lesson: The heart beats in the chest to keep the body healthy. The heart pumps blood through the body providing fresh oxygen and nutrients. Blood is pumped from the heart through arteries to the lungs and back through veins to the heart. The three keys to a healthy heart are to eat good food, get active play and live smoke-free. Home connections Invite students to take home The Circulatory System activity to show their parents or guardians and explain what they learned about the heart. Have students and families use the internet to find animations of the heart and circulatory system. Extension and integration Have students mimic the sound of the heart, and chant, clap, stamp or use musical instruments to beat the rhythm. Invite the school nurse to visit the class. Have students listen to their own hearts using a stethoscope. If available, use a microphone and portable stereo to amplify sounds from the stethoscope so that the whole class can hear. Show a video animation of how the heart and circulation system work. Have the class brainstorm all the facts about the heart that they did not know before. Have students pump water from a squeeze bottle through rubber tubing to see how pressure forces liquid to move. Have students feel the tubing to feel the water pulse through it when the bottle is pumped. Explain that this is similar to blood being pumped through the arteries. Assessment Review students drawings to ensure they can identify and correctly draw and label the circulatory system on an outline of a body. Monitor students responses to the health discussion to ensure they can describe practices that contribute to good health including healthy eating, physical activity and living smoke-free. Have them restate the three keys to heart health. HeartSmart Kids 2015 Heart and Stroke Foundation Grades 2-3 The Powerful Heart 4
the circulatory system The circulatory system is very complex. The heart pushes blood through the arteries to all parts of the body and it returns to the heart through the veins. The lungs let the blood get oxygen from the air and remove waste. The blood carries oxygen and food through the arteries to keep the parts of the body healthy and strong. The blood also carries waste away from the parts of the body. All the parts - the heart, lungs, blood, arteries, and veins - work together as part of the circulatory system. Count slowly from 1 to 26. That s how long it takes your blood to make one entire trip! Use this image as a guide! You could also try laying down on a large piece of paper and have someone trace your outline. Then draw the heart, arteries, veins, and lungs where they would be on your body. You could also use blue and red yarn for the arteries and veins and cut out a red heart and blue lungs and paste them on. Have fun with it!
