The circulatory system is made up of the heart, arteries, veins, capillaries, and blood. It has one main job: to transport oxygen-rich blood from the lungs to tissues and oxygen-depleted blood back to the lungs. There are three main circulatory processes that occur simultaneously: systemic circulation carries blood to the entire body, pulmonary circulation carries blood to the lungs, and coronary circulation provides the heart with its own blood supply. Problems can occur if the blood vessels are damaged or clogged, preventing oxygen from reaching tissues which can lead to conditions like heart attacks.

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.

4. Main Parts of the Circulatory SystemThe main part of the circulatory system is the human heart. There are others important parts. These are:Arteries

5. Veins

6. Capillaries

7. BloodWhat does the Circulatory System Do?The human circulatory system has one job. Its main job is to transport blood and oxygen from the lungs to the other tissues of the body.

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 bodyPulmonary 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 VesselsYour 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.FACTThe Circulatory system has a network of blood vessels over 100,000 Km long. They consist of three things (Arteries, Veins and Capillaries).

11. ProblemsIf 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!
