Transcript

  • 1. Disease Disease is a poor state of health of the body. There are two types of disease:
    • Congenital – inherited disease eg ________
    • 2. Acquired – these are 'caught' as a result of infection or a bad lifestyle. Eg _____________
  • 3. Infectious Diseases
    • Infectious diseases can be spread from person to person.
    • 4. They can be caused by parasitic worms (tiny worms which live inside a host organism and cause disease) or microorganisms.
    • 5. Most infectious diseases are caused by microorganisms, including bacteria, fungi, viruses and protozoa.
  • 6. Bacteria
    • Bacteria are single-celled organisms. The largest bacteria are slightly larger than a red blood cell.
    • 7. As the bacteria feed and grow they give off toxins, which make their host sick.
    • 8. Examples: pneumonia, tetanus and food poisoning.

  • 10. Fungi
    • Fungi are the largest of the four types of microorganisms.
    • 11. Fungus = singular; fungi = plural.
    • 12. Fungi can feed on living or dead matter.
    • 13. Mould, mushrooms and yeast are all fungi.
    • 14. Fungi release tiny spores which pass through the air and start new fungi (like seeds for plants).
    • 15. Diseases caused by fungi include athletes foot, ringworm and thrush.

  • 17. Athletes Foot http://upload.wikimedia.org/wikipedia/commons/4/4a/Athletes.jpg
  • 18. Viruses
    • Viruses are tiny organisms which can only live in host organisms.
    • 19. Viruses force cells to make copies of themselves, and then spread them.
    • 20. Unlike bacteria and fungi, viruses cannot be killed with antibiotics.
    • 21. Examples include influenza (including H1N1 etc), the common cold, chickenpox, AIDS.

  • 22. How Viruses Reproduce http://www.flutrackers.com/forum/attachment.php?attachmentid=326&d=1148840493
  • 23. Protozoa
    • Protozoa are single-celled organisms.
    • 24. They are larger than bacteria and viruses and can grow as large as 1mm.
    • 25. They are more complicated than bacteria and viruses and can do some things animals can do, eg move around.
    • 26. Examples include Malaria and Amoebic dysentery.

  • 28. Work for Today, and Homework
    • Complete questions 1-5 on page 50 (not the “extra”).
    • 29. Read pages 168-171 and the summary on page 162.
    • 30. Answer questions 1,2,4,5 and 7 on page 172.
    • 31. When you have finished, choose a disease and begin researching it. You must have found at least two good websites (remember Mr Farrow's talk) and have shown them to me to confirm your essay topic by the end.
    • 32. If you haven't already, save a new copy of the “G7 Diseases One World Essay Instructions”, re-save it, share it with me and begin completing it.
