With active immunity, the body has cells that produce antibodies to antigens composed of amino acids. The antigen could be a protein itself, or on a virus or bacteria. Once the body has a cell that can produce antibodies to this antigen, it differentiates into memory cells and plasma cells, which are the factories that produce the antibodies.
With passive immunity, just the antibodies are given, such as an injection. Mothers also confer passive immunity to their children through breast milk. IgA (one of the 5 antibody classes) is secreted. This is temporary as it will bind the antigen, but will not induce production of their own protective antibodies.
Passive natural immunity
Natural Passive Immunity
passive
active immunity is the immunity that is stimulated internally as a a result of antibodies entering the body. Passive is stimulated by substances from an external source
Passive immunity is different from active immunity because it means that you can get it from another person and you can give it someone else. Active immunity is when you get it by yourself, not from another person, and you cannot pass it to another person.
One is active and one is passive
active acquired immunity and passive acquired immunity
yes
Active immunity is generated by your body. So you get active immunity as a result of infections or due to vaccines. Passive immunity is not generated by your body. Here the antibodies are to be supplied. Child gets the antibodies from mother. Alternately you get the antibodies via injections. The effect of active immunity is long lasting. The effect of passive immunity is short lived. So the active immunity is considered as better. The passive immunity has one advantage. It is available with immediate effect, while it takes about two to three weeks, before the effects of active immunity is available.
passive and active
active
Both passive and active immunity have role in the elimination of bacteria and naturalization of toxins. Extracellular bacteria G+ and G- induce inflammation and production of toxins. Hence, active immunity responses by production of antibodies and passive immunity via phagocytes and complement activation, cytotoxic production by macrophages.
