Lesson 14 The Pumping Heart HBS, pp. 110-119 Reference: SI, pp. 486-495 Name/ Per.__________________________________ Lesson Objectives: 1. Use a model to explore the double pump action of the heart. 2. Determine the direction of the flow of blood thru the heart. 3. Recognize that humans have a closed circulatory system. 4. Study the structure of the heart. 5. Explain the differences between pulmonary and systemic circulation Introduction 1. How does blood move thru the body? Pre-Inquiry “Getting Started “Questions 1. How many chambers does the heart have? ____________ 2. Blood going away from the heart travels in _______________________, while blood being carried to the heart travels in ____________________. Inquiries 14.1 Analyzing the Siphon pump Heart Model 1. What makes the water begin to flow thru the pump? 2. Through which tube the stiff one or the flexible one does water enter the pump? 3. What keeps the water from flowing back thru the tube when you release the bulb? 4. Listen closely as you release the bulb? Can you hear clicking sounds? If so what appears to be causing them? 5. Label the structures on the heart and relate parts to the pump model on Diagram. 6. Draw arrows to show how blood flows from the heart to the lungs to the heart and then to the body again. Post-Inquiry “Reflections” Questions Listen to your heart. What causes the sound you hear in the stethoscope?
