What is the Heart?
The heart is a muscle about the size of your fist, and it works non-stop to keep you alive. It’s an exceptionally strong pump that pushes blood carrying oxygen and nutrients around your body. Pretty cool, right?
What is the structure of the Heart?
Use resources from the lesson pack to make the experience real by constructing heart models or carrying out a heart dissection.
Children will be fascinated to see what a real heart looks like inside while they explore how everything fits together to keep blood flowing through this powerful organ.
You'll spot:
- four chambers: two on top (atria) and two on the bottom (ventricles).
- two valves (like little doors)
- arteries (big tubes that carry blood away from the heart) and veins (big tubes that carry the blood to the heart).
Check out a KS2 heart diagram to see how it works!
