TRANSPORT IN HUMANS

1. Understand the importance of a transport system in multi-cellular organisms.
2. Know why the transport system in an amoeba is so different from a human, and why humans cannot adopt a similar system as the amoeba.
3. Explain why the transport system in mammals is also known as the circulatory system.
4. Understand that any system is connected to other systems, both internally and externally, and the output from one part of a system (which can include material, energy, or information) can become the input to others. Such feedback can serve to control what goes on in the system as a whole.
5. Know that blood is pumped around the circulatory system by the action of the heart.
6. Know that the heart is a muscular organ which requires its own supply of oxygen and nutrients (via the coronary arteries).
7. Label and identify the principle structures of a mammalian heart, including the valves within it and the inter-connecting blood vessels & associated valves.
8. Trace the path of blood through the circulatory system, in particular the pathway of oxygenated and deoxygenated blood through the heart.
9. Know the structure and function of arteries, veins and capillaries.
10. Compare and contrast the structure of arteries and veins, and state how they are adapted for its function.
