1. The Heart as a Pump LO: - to label the structure of the circulatory system to explain how the heart pumps blood around the body http://youtube.com/watch?v=N_LuJGobrpw&feature=related http://youtube.com/watch?feature=related&v=1SBMgh7IVGg Respiration recap 1. List 2 activities where aerobic respiration occurs? 2. List 2 activities where anaerobic respiration occurs? 3. How do oxygen and glucose get to cells for respiration to occur? Next time blood and circluation heart a different lesson

2. Circulatory System Blood- carry important substances around the body eg. ________, _________ to cells for __________. Blood vessels -tube ________ travels through Heart- pumps or pushes blood around the ______ Blood, oxygen, respiration, glucose, body

3. Blood vessels Arteries- thick walled carry oxygenated blood away from the heart Capillaries – one cell thick where substances are exchanged by diffusion Veins- thin walled with valves, carry deoxygenated blood back to the heart Path od red blood cell video

4. Plasticization- blood vessels

5. Circulation Heart is a double pump Left side pumps oxygenated blood to body Right side pumps ___________blood to the lungs Label the capillaries on the diagram and trace with your figure the path blood takes

6. right atrium Left ventricleRight ventricle Left atrium Pulmonary veins Vena cava (vein) Pulmonary arteries aorta Right atrioventicular valve Left atrioventicular valve Semi lunar valves

7. The blood is the bodies taxi service- blood mobile What does it pick up and transport around the body? Where does it pick these substances up and where do these get dropped off? What roads (blood vessels) does it travel through? These words may help you Destination -lungs -Body cells Roads Arteries Capillaries Veins Passengers O G C D W Remember the blood must always go thru the heart on its journey TASK: Tell the story of the blood taxi journey

8. Read stories

9. Heart To left lung To right lung Oxygenated blood to the body Deoxygenated blood from the body Oxygenated blood from the lungs Label your diagram of the heart Heart has 4 chambers 2 ventricles 2 atrium Blood enters thru the atria

10. Lungs Left side of Heart Cells Right side of Heart O2O2 Key RBC = Red blood cells RBC Pushes RBC RBC O2O2 CO 2 Pushes RBC RBC CO 2 RBC Start Here
