Lesson Details
Key learning points
- Substances are transported around the body in the blood.
- Blood is pumped through blood vessels by an organ called the heart.
- The heart is made of cardiac muscle, which continually contracts and relaxes to pump blood.
- The heart has four chambers with valves, which keep oxygenated and deoxygenated blood separate.
- We have a double circulatory system; blood is pumped to the lungs for gas exchange then around the rest of the body.
Common misconception
Confusion between the names and functions of the different parts of the heart and the direction that blood moves through the heart.
The parts of the heart and their structure and function are dealt with separately and clearly, and followed up with quick checks plus longer and more detailed tasks.
