the skin keeps out most pathogens
AIDs.
the disease invades them and our body
White blood cells are the good cells in the body. Yes you do need red and white blood cells, but the white ones fight off diseases or pathogens. If white blood cells cannot do this then the immune system fails. The pathogens depending on their severity, could hurt the body very much. Doctors do different tests and procedures to help this not happen. White blood cells are needed to protect the body from pathogens. When they cannot stop the invading pathogens, a person will most likely get sick. on NovaNet I'm pretty sure that the answer is the person will die:))
Phagocytes
then antibodies are produced to help If the blood cell did not able stop the pathogen then it will result in disease or toxicity which will make the person ill and may be it can result in immunity for feature
White-Blood Cells. Either Pathogens, or Lymphocytes.
White blood cells attack, engulfs and kills pathogens. Various types of white blood cells exist and each one is specialized on killing different types of pathogens. There are white cells that kill pathogens that cause acute infections while others target pathogens that cause chronic infections. The proportion of white cells found on examinationod blood sample could suggest the nature of infection we are dealing with.
No, the white blood cells are divided into many types of specialized cells. The Macrophages, Granulocytes, Natural Killer cells and Dendritic (Lagerhans) cells are part of the immuno response system's first line of defense: Macrophages kill any type of pathogens they recognize as not welcome, while the Neutrophile Granulocytes are experts in bacteria killing. Dendritic cells alert the adaptive immuno response system such as T-cells. Cytotoxic T-cells then kill tissue cells infected by pathogens, and so does Natural Killer cells (but does not touch the pathogens themselves). They do not have to be activated first, but are able to find infected/sick cells by themselves, which makes them effective cancer-killers. Also, by killing infected cells they prevent growth and proliferation of more pathogens in the body. Regulatory-T-cells (suppressor cells) and T-Helper cells does not kill pathogens themselves but regulate the rest of the white blood cells.
Bleach will kill most blood borne pathogens.
Substances present in the blood that can cause infection or disease. Hepatitis B and hepatitis C viruses are bloodborne pathogens since they are spread through blood and can cause a liver infection.
