Analysis Questions
1. Look at figure 2 on page B44. This is a simplified map of how blood travels around your body. Use your finger to trace one of the possible paths of blood flow. Begin in the left side of the heart (your right) and stop once you reach the left side of the heart again. Be sure to go in the direction of the arrows. Record which organs and structures you passed through in your path. (skip 4 lines)

2. Which organs does the blood have to pass through each time it goes around the human body? Why do you think blood always has to pass through these organs? (skip 6 lines)

3. Complete the following table (skip 8 lines)
