  • Three things I like about this powerpoint are the choice of background, creativity and interesting content. Two things need to be improved are more pictures and shorten the content into point form. One question I would like to ask is what are antibodies. (:

Transcript

  • 1. OD BLO ND A D S O L LO SEB S VEJAVIN, IZZA, SEAN.
  • 2. BLOOD VESSELS• Arteries• Veins• Capillaries
  • 3. ARTERIES• Tough on the outside and smooth on the inside.• Has three layers: an outer layer of tissue, a muscular middle, an inner layer of epithelial cells.• Deliver the oxygen-rich blood to the capillaries where the actual exchange of oxygen and carbon dioxide occurs.
  • 4. VEINS• Transport blood at a lower pressure• Have three layers: an outer layer of tissue, - muscle in the middle, - a smooth inner layer of epithelial cells.• The layers are thinner, containing less tissue.• Veins receive blood from the capillaries after the exchange of oxygen and carbon dioxide has taken place.
  • 5. CAPILLARIES• One cell thick• Enable the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste chemicals between blood and surrounding tissues.
  • 6. ABOUT BLOOD• Transport oxygen and nutrients to the lungs and tissues.• Forming blood clots to prevent excess blood loss.• Carrying cells and antibodies that fight infection.• Bringing waste products to the kidneys and liver, which filter and clean the blood.• Regulating body temperature.
  • 7. TYPES OF BLOOD:• Plasma• RBC (Red Blood Cell)• WBC (White Blood Cell)• Platelets
  • 8. PLASMA• Transport blood cells throughout your body along with nutrients, waste products, antibodies, clotting proteins, chemical messengers and proteins that help maintain the bodys fluid balance.
  • 9. WHITE BLOOD CELL• White blood cells protect the body from infection.
  • 10. RED BLOOD CELL• Red cells contain a special protein called haemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled.
  • 11. PLATELETS• Platelets help the blood clotting process by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur.• This results in the formation of a fibrin clot, which covers the wound and prevents blood from leaking out.• Fibrin also forms the initial scaffolding upon which new tissue forms, thus promoting healing
