Human defence system
- Immunity=the ability to resist
infection
- General defence system acts as a barrier to all pathogens
- First line of defence: skin, clotting,lysozyme, mucus, cilia, acid, beneficial bacteria
- Second line of general defence: Phagocytic white blood cells
- Large phagocytes are called
macrophages - they surround and ingest pathogens
- Defence proteins:
COMPLEMENT (destroys viruses) AND
INTERFERON (prevent viral multiplication)
- Inflammation - brings white blood cells to area and causes fever
- Large phagocytes are called
macrophages - they surround and ingest pathogens
- Second line of general defence: Phagocytic white blood cells
- First line of defence: skin, clotting,lysozyme, mucus, cilia, acid, beneficial bacteria
- Specific defence system attacks particular pathogens
- Monocytes
Nota:
- m
- Production of antibodies by Lymphocytes
- An antibody is a protein produced by white blood cells in response to a specific
antigen
- An antigen is a foreign molecule that stimulates the production of
antibodies
- An antigen is a foreign molecule that stimulates the production of
antibodies
- An antibody is a protein produced by white blood cells in response to a specific
antigen
- Monocytes
- General defence system acts as a barrier to all pathogens
- What is induced immunity?
- The ability to resist disease caused by specific
pathogens by the production of antibodies
- Active Immunity - the production of a person's own antibodies in
response to foreigh antigens that enter the body
- Natural active immunity e.g. getting chickenpox
- Artificial active immunity is when a pathogen is medically introduced into the body -VACCINATION
- A vaccine is a non disease-causing dose of a pathogen or its toxin which triggers the
production of antibodies
- A vaccine is a non disease-causing dose of a pathogen or its toxin which triggers the
production of antibodies
- Natural active immunity e.g. getting chickenpox
- Passive Immunity
- When individuals are given antibodies that were formed by another organism
- Natural passive immunity: child gets antibodies from mother across placenta or from breast milk
- Artificial passive immunity is when a person is given an injection containing
antibodies made by another organism e.g. anti-tetanus injection
- Natural passive immunity: child gets antibodies from mother across placenta or from breast milk
- When individuals are given antibodies that were formed by another organism
- Active Immunity - the production of a person's own antibodies in
response to foreigh antigens that enter the body
