False, because you can make antibodies via immunizations given by a doctor.

the lymphatic
the muscular
the cardiovascular
What is the function of antibodies within the immune system?
Antibodies kill off any antigen that enters the body.
Antibodies are only made when you are given a vaccination for specific antigens.
Antibodies bind to specific antigens to flag for destruction.
Antibodies are part of an external defense mechanism.
Which of the following statements are TRUE about vaccinations?

Triggers the body to make memory cells for specific pathogens.
They are substances prepared from killed or weakened pathogens.
Always allows the body to resist an infectious disease any time it comes into contact with it.
All of the following are examples of white blood cells EXCEPT

Skin
Mucus
Inflammation
Saliva
Sweat

T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.
T cells only make memory cells, and B cells only make antigens
T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.
T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
