how does residental normal flora protect the body against pathogens
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.
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.
NEUTROPHILIS
White-Blood Cells. Either Pathogens, or Lymphocytes.
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.
White blood cells are those phagocytes that engulfs the damaged cells or pathogens entering the body's tissues.
They are similar because they both protect the body and fight against pathogens.
PhagocytosisPhagocytes make up three-quarters of the body's white blood cells. They destroy pathogens by engulfing them.It's called phagocytosis. Macrophages mainly phagocytose the pathogens.
the white blood cell protects the body against invading pathogens.
Phagocytes
white blood cells, called lymphocytes, destroy pathogens and protect against future infections.
