Lesson Details
Key learning points
- Blood vessels transport blood all around the body, to and from your heart.
- Arteries are blood vessels. Most arteries deliver blood rich in oxygen to all the parts of the body.
- Veins are blood vessels. Most veins return blood low in oxygen to the heart.
- Blood is always red. Blood travelling through veins may appear blue because of how light travels through our skin.
- Scientists use scientific diagrams to describe different systems in the human body.
Common misconception
Pupils often think that blood sloshes around inside the body rather than travelling through different types of blood vessels. Pupils may also think that blood can be red or blue.
The learning cycle focusing on representing blood vessels in the human body helps pupils to understand that blood vessels are often drawn in different colours merely to help us distinguish between them and understand their different functions.
