Transcript

  • 1. The Circulatory System and Blood<br />By Arefeh Hosseini<br />
  • 2. The Heart<br />The heart is a muscular organ in the body<br />Its function is to pump blood to the rest of the body <br />The heart consists of two chamber, the right and the left.<br />The right is relatively smaller because it receives the de-oxygenated blood and the left spreads the oxygenated blood.<br />
  • 3. The Lungs<br />The lungs two spongy organs that sit inside the chest, on either side<br />Their function is to replenish the blood’s oxygen and rid of waste or carbon dioxide<br />The lungs are very important as they are also part of the respiratory system<br />
  • 4. Arteries<br />Arteries are thick vessels that lead from the heart and spread to every part of the body<br />They branch into finer part until they reach capillaries<br />Arteries are always carrying blood, containing lots of oxygen and glucose <br />This supplies the body with the needed amounts of supplies<br />
  • 5. Capillaries<br />Capillaries are super thin vessels<br />They are so thin in fact that glucose and oxygen are able to diffuse through them <br />These then are able to distribute the energy and oxygen<br />They then soak up (diffusing) blood that contains carbon dioxide that is what is created when the oxygen is used by the body<br />
  • 6. Veins <br />The veins are vessels thickening as they approach the heart<br />Their job is to take blood that has been used and contains carbon dioxide back to the heart<br />The pulmonary vein carries the de-oxygenated blood to the lungs, this is where the exception of veins occurs as they go from the heart to the lungs<br />
  • 7. RedBlood Cells<br />Red blood cells are a component of blood that runs through veins and arteries<br />These cells carry oxygen and glucose, but they also return waste known as carbon dioxide<br />They spread the food we eat and the air that we breath to the rest of our bodies<br />The tiny biconcave RBC&apos;s contain oxygen that attaches haemoglobin to be carried around the body.<br />
  • 8. White Blood Cells<br />White blood cells are a component in the blood<br />Their function is to rid the body of germs, infection and diseases<br />They do this by almost swallowing and engulfing the germs in the antibodies that they carry<br />This eliminates diseases and infection and helps us stay healthy<br />They are part of the immune system also<br />
  • 9. Platelets <br />Platelets are a vital component of blood<br />They are the clotting factor<br />Their exact function is to rush to the area that a cut or a bruise has occurred<br />They next begin to bond and harden the blood that is flowing from the wound<br />Eventually they stop the blood<br />Without platelets men may die and women too once their menstrual cycle begins<br />
  • 10. Plasma<br />Plasma is the largest component of blood as the other components are embodied within it<br />The plasma is a straw coloured liquid containing the red and white blood cells as well as the platelets<br />However waste or carbon dioxide, water, and nutrients are also carried around the body in the plasma<br />
