Blood and Blood Vessels

  1. 1. Done By : Ginnie , Julia , Sheng Jie & Brandon
  2. 2. Main blood vessels connected to theheart Arteries Veins Capillaries
  3. 3. Contains 3 layers• An outer layer of tissue Arteries• A muscular middle – elastic and very strong• An inner layer of epithelial (tissue that covers a surface ) cells- smooth so that blood can flow easily with no obstacles in its path• Carry blood away from the heart• Contains blood under high pressure
  4. 4. VeinsCarry blood to the heartHave valves to prevent blood flowing backwardsTransport blood at a lower pressureHave thin layers of walls Transport waste-rich blood back to the lungsand heart
  5. 5. outer layermuscle layer elastic layer valve inner layer
  6. 6. CapillariesMicroscopic – one cell thickFound in the muscles and lungs When gas exchange takes place, oxygenpasses through the capillary wall and theninto the tissues, carbon dioxide passesfrom the tissues into the bloodstream andtransport back to the heart.
  7. 7. Blood Blood Transport food , oxygen , water and mineral salts throughout the body. Carry away carbon dioxide & waste products Helps keep body at the right temperature
  8. 8.  Carries hormones to the body’s cell Sends antibodies to fight infection Hemoglobin from red blood cell helps carry oxygen throughout the lungs, the excess carbon dioxide is then exhaled through the lungs
  9. 9. Platelets Platelets• Clump together to form clots• Clotting stops the blood from flowing out of the body when a vein or artery is broken.
  10. 10. White Blood Cell• An important part to the immune system• They produce antibodies and destroy harmful micro- organisms
  11. 11. Fun Facts Fun Facts!! Did you know ?If you took all of the blood vessels out of an average child, and laid them out in one line, the line would be over 60,000 miles long!An adult’s vessels would be closer to 100,000 miles long!
