  1. Circulatory System By: Tomas Cortes

  2. Where is it and What does it Do? • It’s located Throughout the whole body • It is called the Body’s Transportation System aswell as the cardiovascular system • The systems is responsible for the flow of: • Oxygen • CO2 • Other gases • Hormones • Waste products • Nutrients

  3. Main Organs-Heart • The HEART– It is the Pump that makes it all work • It has four chambers or sections: • two atria and • two ventricles • These sections are made out of cardiac muscle. • The heart is split in two halves: • Right Side - Receives blood full of CO2 from the body and Sends it to the lungs. • Left Side – Receives Oxygenated blood from the lungs and Sends it to the body

  5. Blood Vessels • Arteries: Take blood away from the heart. They have very thick walls so that they can take all the power that is produced by the heart. • Veins: Take the blood back to the heart. Don’t have thick walls, thin walls and more space for blood to flow. • Capillaries: Tiny blood vessels that are as thin as a hair or thinner. Capillaries connect arteries to veins. Nutrients, Oxygen, Co2 and other wastes go in and out though the thin walls.

  6. Blood • Blood contains four major things: • Erythrocytes (red blood cells) • Leukocytes (white blood cells) • Platelets (it is what stops you from bleeding to death from a paper cut, it helps your blood clot or dry up.) • Blood plasma (it is what the rest of the components of blood lie on) Did you know that one drop of blood has around 50 million red blood cells, 100,000 white blood cells, 2.5 million platelets yet the biggest component of blood is the blood plasma.

  7. Different Types of Circulation • There are three types of circulation: • Coronary circulation: It’s the circulation inside the heart. It brings in nutrients and lets out waste. • Pulmonary Circulation: The circulation in between the blood and lungs. Redbloodcells drop of Co2 and pick up O2 to take to the heart. • Systemic circulation: It’s the circulation thatgoes all over you body. • Did you know that in pulmonary circulation the oxygenated blood goes in veins to the heart and blood cells that don’t have oxygen travel in arteries to the lungs. In the other types of circulation arteries carry the oxygenated blood and veins carry the oxygen lacking blood.

  8. Diseases-Blood Pressure • The pressure that heart provides for the blood to go out to the lungs and body and to come back. There are two types of pressure measured: • Systolic (the higher number) is the pressure created when the heart contracts (sends blood to lungs and body) – Under 120 is considered healthy • Diastolic (lower number) is the pressure when the heart relaxes and the blood flows back into the heart from the body and lungs

  9. Systolic and Diastolic Pressure

  10. How to Keep it Healthy • Eat nutritiously • Healthy snacks • Very little Fast Food • Do not become obese • Some Fats and oils are very unhealthy – learn which ones. • Do exercise regularly • Exercise more watch TV less • Do NOT smoke • Try to keep a low stress level

  11. Relationship with other Systems • The circulatory system is related with three other systems. • The inmune system because inside blood there are white blood cells and platelets. They belong to the inmune system now that platlets try not to let infections in though your blood and white blood cells fight the germs and bacteria that manage to get into you system. • The urinary system because before blood goes back to the heart capillaries drop of solid waste in the kidneys to get peed out • The respiratory system because it drops of O2 at cells so that they can do cellular respiration in the mitochondrias and pick up Co2 that is produced after the mitochondiras burn up sugar to create energy and in the process let out Co2.
