4. the presence in the body of the virus that cuases AIDS
by eating wrong!
They make you bleed to your death so you can't get pathogens.
the immune system
Antitoxins
Tonsils help defend the body against infections by trapping and filtering out bacteria and viruses that enter through the mouth and nose. They play a role in the immune response by producing antibodies to fight off these pathogens.
The main function of white blood cells (also commonly referred to as leucocytes) is to defend against foreign invading pathogens that may enter the body. They do this as they are phagocytes, in that they engulf pathogens and destroy them. Therefore, the function of a white blood cell is to defend the body against infection.
Washing your hands and face is a defensive reaction. it help defend your body against infection by pathogens.
They don't defend pathogens. They defend *against*pathogens. They poison them, they burn them with ozone / hydrogen peroxide / sodium hypochlorite / chorine dioxide, and then they eat them whole if necessary.
They can fight them using white blood cells to create anti bodys.
B cells make antibodies that grab on to the antigens and make them clump together then something eats them.
When someone has AIDS there adaptive immunity (the immunity that remembers previous infections) is severely compromised. The adaptive immunity is responsible for remembering previous infections and dealing with them. Since the immune system is so weak and has a bad memory of previous infections it takes a much longer time for your body to defend against new pathogens along with previous pathogens that your body currently has and is no longer able to manage.
its role in defending your body against disease is to find and "eat" (consume i guess) bacteria, viruses, and dead or injured body cells Phagocytes defend the body by destroy pathogens. They surrounding and engulfing them.
