UNIT 10 Cardiac and Respiratory Systems
Essential ideas:
The blood system continuously transports substances to cells and simultaneously collects waste products.
The lungs are actively ventilated to ensure that gas exchange can occur passively.

- How many different types of cells are found in human blood?
- What are the differences between an artery and a capillary?
- How does blood flow round the body? How could you investigate that?
- Why do arteries have thick stretchy walls?
- What is the advantage of thin walled, leaky capillaries?
- Which parts of the circulatory system have valves?
- What is meant by the term, 'double circulation'?
- How does blood flow through the heart?
- Where is the heart's pacemaker?
- How does the body control the rate of the heart beat?
- How do the lungs increase the rate of gas exchange from alveoli and the blood?
- What type of cells make up the walls of alveoli?
- What are the muscles which enable ventilation?
