An introduction to the human heart, its location within the human body and its function as a pump. The heart sits within the chest cavity between the lungs and is about the size of a fist. Essentially it is a muscle which functions as a really powerful pump. The heart takes in blood low in oxygen from the body. It pumps it through the right side of the heart and on to the lungs. In the lungs the blood passes through very small blood vessels and absorbs oxygen. The freshly oxygenated blood is pumped back through the heart and on to the rest of the body where the oxygen provides fuel for muscles and organs.
This clip can be used as a stimulus or reference to explain the uses of the heart. Teachers could use this clip to highlight the position of the heart within the body. They could also open discussions based on what the children have learned from watching the clip. Questions could be asked about how the heart works and the importance of it for the rest of the body.
