The Human Circulatory and Respiratory Systems Objective Students will understand the components and functions of the human circulatory and respiratory systems, and how they are related. National Science Education Standards
Understandings about Scientific Inquiry Matter, Energy, and Organization in Living Systems Warm-Up 1. Ask students to guess which structures of the body, if laid end to end, would have a total length of more than 60,000 miles, or two and a half times the diameter of Earth. (Answer: blood vessels which include arteries, veins, and capillaries) 2. Ask students to guess how many gallons of blood the heart pumps in a day, and guide them by telling them to guess "higher" or "lower" until they guess the answer (about 1000 gallons per day). 3. Ask students to think back to when they were little, and to raise their hands if they ever remember telling their parents they were going to hold their breath if they didn't get their way about something. Next ask them why they think that didn't work out so well, and remind them that should be thinking of physiological reasons. Assessment Have students work in small groups. Tell them they are a public relations team who have been assigned the task of creating a travel brochure which advertises tours of the human circulatory and respiratory systems. The brochure should contain information about the components and functions of each system, how the systems are related, and should contain the words in this lesson that are in bold type. Students may also need to do additional research to find interesting facts to use in promoting their tour. Ask students to present their brochures to the class.
