1. HOW DO ANTIBODY KILLS BACTERIA Prepared by: Firdaus, hairi, naim, zaid, faiz, zaeck Bac. Of Medical Technology (Part 1) )

3. Structure of Antibody

12. Ab-Ag interaction

17. - If harmful bacteria enter the body - they cause damage by either damaging the cells around them or by releasing toxins (poisons) that make us ill. bacteria

18. The harmful bacteria cross into the blood vessels where they are attacked by white blood cells which are part of the immune system. A blood vessel in the body. White blood cells bacteria

19. There are two types of white blood cells called phagocytes and lymphocytes. bacteria A blood vessel in the body. Phagocytes Lymphocytes

20. bacteria A blood vessel in the body. Phagocytes because of their shape can “eat” bacteria. Phagocytes

21. Phagocytes because of their shape can “eat” bacteria. A blood vessel in the body. Phagocytes

22. Phagocytes because of their shape can “eat” bacteria. A blood vessel in the body.

23. Phagocytes because of their shape can “eat” bacteria. A blood vessel in the body.

24. Phagocytes because of their shape can “eat” bacteria.

25. A group of lymphocytes produce proteins called antibodies. A blood vessel in the body. antibodies

26. A blood vessel in the body. Antibodies kill the bacteria in different ways. One way is to make them clump together so that they are easily “eaten” by phagocytes. antibodies

27. Antibodies kill the bacteria in different ways. One way is to make them clump together so that they are easily “eaten” by phagocytes. A blood vessel in the body.

31. Antibodies kill the bacteria in different ways. One way is to make them clump together so that they are easily “eaten” by phagocytes.

32. Antibodies can also promote/facilitate killing of the bacteria in co-operation with another protein called complement . A blood vessel in the body.
