6. Describe the path that blood travels through your body. Begin by describing how the heart works as a pump. Then describe how blood is oxygenated and transported to the body’s cells. Last describe how waste products are removed from cells by deoxygenated blood.

c. The heart – __________________________________________________________________

7. Colour and label the diagram of the heart.a. Label the following parts of the heart:

b. Draw arrows to show the path blood takes through the heart in both directions. The first one has been drawn for you.

c. Colour the oxygenated side red and the deoxygenated side blue.
