3. Introduction • The Circulatory System is the main cooling and transportation system for the human body • The body has about 5 liters of blood continuously traveling through it by way of the Circulatory System • In the Circulatory System, the heart, lungs, and blood vessels have to work together • The Circulatory System has three different parts: pulmonary circulation (lungs), coronary circulation (heart), and systemic circulation, (the rest of the system’s processes).

4. The Heart This organ is what pumps oxygen rich blood, nutrients, hormones, and the other things your body needs to maintain your health, to your organs and tissues. The pulmonary veins you see on the right side of the diagram come from your lungs, where the blood cells collect oxygen. It’s then pumped out to the rest of the body through the Aorta (Top). All of the blue sections show blood cells carrying waste, (C02) moving back to the lungs (where the C02 will be replaced by oxygen) through the Pulmonary Artery (Top, blue) Pulmonary Artery (Superior Vena Cava) From the Body (Aortic Artery) To the body Pulmonary Veins Valves: (tricuspid valve semilunar (pulmonary) valve, bicuspid (mitral) valve, and the semilunar (aortic) valve (Inferior Vena Cava) From the Body By The Way… Whenever the blood is pumped from one section of the heart another a valve closes behind it preventing the blood from moving backwards.

5. Blood Flow through Heart • Blood from the body travels into the right atrium, moves into the right ventricle, and is finally pushed into lungs in the pulmonary arteries • The blood then picks up oxygen and travels back to the heart into the left atrium through the pulmonary veins • The blood then travels through the to the Left Ventricle and exits to the body through the Aorta… Left Atrium Right Atrium

6. Blood Flow to Arms • Oxygen rich blood leaves the heart and travels through arteries • In the capillaries the oxygen and food is given to the body’s cells • The blood finally travels back through veins to the heart to pick up oxygen ARTERIES- FROM HEART CAPILLARIES VEINS- TO HEART

7. Path to the Exchange Pulmonary Vein Aorta A red blood cell then travels from the heart through arteries that eventually branch into the body’s vast system of capillaries (microscopic blood vessels which connect arteries and veins), they eventually lead to… Brachial Artery Renal Artery Redial Artery Ulnar Artery Iliac Artery

8. TRANSACT When the itty bitty teeny tiny red blood cells pass the desired tissue they………………………………. Oxy-Rich Blood Cell Tissue The Exchange The oxygen the blood cells are carrying is given to the body’s tissue. Tissue And the CO2 (waste) from the tissue is given to the same blood cell to be exhaled. Oxy-Poor Blood Cell Technically the Hemoglobin in the blood (a substance full of iron) attracts oxygen from the lungs. The red blood cell then carries it to the desired tissue. Because this tissue has a high CO2 count the hemoglobin lets go of its oxygen and collects the carbon dioxide. You see the hemoglobin has an affinity for whichever gas has a greater count. Because the tissue has a large amount of built up waste (CO2) the hemoglobin attracts it and then replaces it with oxygen, and vise versa in the lungs. How It Works… Now lets travel to the legs!!!

9. Blood Flow to Legs !FUN FACT! • Approximately 500 ml of blood moves from the heart and lungs down to the legs when a person stands up after lying down • The oxygen rich blood cells then travel through the capillaries where yet another…

11. Gas Exchange Occurs, The oxygen and CO2 are exchanged…in the cells Oxygen Rich Tissue Don’t forget that the Hemoglobin in the blood cells let go of the cell’s oxygen because of the large CO2 (waste) count in the tissue. Oxygen Poor Oxygen Rich Oxygen Poor Now lets go back to the heart!!!

12. Circulation back to Heart To upper body • Capillaries carry the blood to… • Venules that connect to veins and the… • Veins (wide blood vessels) carries the oxygen-poor blood back to the heart. From upper body To lung To lung From lung From lung Right Atrium Left Atrium Right Ventricle Left Ventricle From lower body To lower body

13. Conclusion As you have learned (Hopefully) the Circulatory System is one of the most important systems in the human body… It is the only reason you’re still alive today… and you can attribute the cooling down, feeding of and protection of your body to it. So the next time you bust open your leg skateboarding you can thank your Circulatory System for patching you up.
