phagocytosis
blood serum containing antibodies against specific antigens; provides immunity to a disease
The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.
Pathogens are the disease causing agent while antigens are found in the antibodies that fight against the pathogens. So in short, no they aren't the same.
your body produces antigens to fight against the pathogens and imune you agaist diseases.
It is an acquired immunity
They are similar because they both protect the body and fight against pathogens.
Antigens are important because they trigger responses to pathogens by the immune system. Without them, no prevention against pathogens would take place.

Active immunity
You exhibit Active Immunity when cells encounter anitgens and produce antibodies against them.
Active immunity
Clonal expansion is the process that provides many B cells and T cells that are activated against specific antigens. Clonal expansion is what provides the immune system its strength.
