3. The Circulatory System The circulatory system is made up of blood vessels and muscles that help control the flow of blood around the body. This process is called circulation.
8. How the Circulatory System Works There are 3 steps that all happen at the same time within the body. Systemic Circulation – Where the blood is moved around the body Pulmonary Circulation – Where the blood is carried to the lungs Coronary Circulation - This provides the heart with its own supply of blood
9. Blood and Heart Vessels Your blood travels around your body in tubes called blood vessels Your blood goes from your heart into your arteries then travels around your body
10. Blood and Oxygen Blood is pumped into the right side of the heart. It goes to the lungs and gets oxygen and leaves through the left of your heart and goes to all of the body cells. FACT The Circulatory system has a network of blood vessels over 100,000 Km long. They consist of three things (Arteries, Veins and Capillaries).
11. Problems If the Arteries, Veins and Capillaries don’t work you will not get oxygen pumped through your body and you will have a heart attack. If you eat a lot of take away foods, food that is very high in acid (e.g. tomatoes, fried food, vinegar, oranges) you will get a heart burn. If you smoke, eat high fat foods, drink a lot of alcohol you will clog your arteries and you could get cancer and have a heart attack!
12. Taking Care Do not smoke Eat healthy Drink healthy Don’t take drugs Exercise
