  1. Animals including Humans Year 6 Lesson 2 LI: To identify and name circulatory system and its function.

  2. Input Double circulatory system What does this term mean?

  3. What is a double circulatory system? • A double circulatory system has two cycles that work together to keep us alive. • Systemic system (left) • Pulmonary system (right) • The systemic circulatory system carries the oxygenated blood (blood with oxygen) from the lungs to the heart where it is pumped to the rest of the body. • The pulmonary circulatory system carries deoxygenated blood (blood without oxygen) from the body to the heart where is pumped back to the lungs to get oxygen.

  4. Drama Lungs Heart Body

  5. The Circulatory System Using what you have learnt in the drama, talk your partner through what this diagram shows

  6. Activity Colour in the double circulatory system to show where oxygenated and deoxygenated blood is found. Label the systems either systematic or pulmonary.

  7. Activity • Now write a paragraph explaining the two different systems answering these questions: • What are the two systems called? • Why do we have two? • Where are the two systems found in the body? • What type of blood do the systems carry? • What route around the body do the systems take?

  8. Plenary William Harvey was the first scientist to describe the circulatory system where the blood was pumped to the brain and the body by the heart. Before William Harvey, scientists thought the blood just flowed randomly around the body.
