Name _________________________________________ Date _______________ Class ____________ Cardiovascular, Respiratory, and Digestive Systems The Cardiovascular and Lymphatic Systems VIDEO SUMMARY This video presents an inside look at the cardiovascular system, with images showing the interior of the heart and blood vessels. The heart is essentially a muscle that functions as a very powerful pump. It pumps blood throughout the body, first into the lungs, then back through the heart, and then out to all parts of the body. The oxygen from the blood provides fuel for the muscles and organs within the body. After you have watched the video, write your responses to these questions. 1. Where is the heart located inside the chest cavity? Based on the functions of the cardiovascular system, why does this location make sense? 2. Why is it important to understand that your heart is a muscle? What does that fact tell you about how you can protect the health of your heart? 3. Based on the information in the video, what risks do you think smoking and exposure to secondhand smoke pose to the health of your cardiovascular system?
