The antigens are what ordinate the body that in is in position a foreign invader. If a person already has the antibodies for a certain antigen so the invader will be neutralize instantly, and then eaten by a macrophage. As said if the antigen is raw(a) then a great process goes in to affect.

at that place are 2 divergent responses, the Cellular response and the humoral response. The Humoral response starts when a macrophage sees and engulfs the invader. The macrophage then displays the antigens of the invader on itself. It then starts the friend T-cells. The helper T-cells recognize what the antigen(s) look like. The avail T-cells then activate the B-cells. withal the Helper T-cells activate the killer T-cells as go hazardous of the Cellular response. The B-cells also...
