Describe how the process of immunization works (P4)
Vaccination leads to produce the white blood cells into the body for its protection against pathogens. Vaccination process consists of injecting a pathogen dead in the body. People in this way can be immunized against the live pathogens. These act as antigens, which once injected in the body encourage white blood cells for producing antibodies. Pathogens stimulate by white blood cells called lymphocytes to produce antibodies to destroy it. Once antibodies from pathogen and lymphocyte are touching each other, more lymphocytes will be rapidly produced. If the person leads to be infected by the same pathogen the immune system is prepared.
A phagocyte is a cell that can protect our body against pathogens. It is composed of lysosomes which contain enzymes. This phagocyte when meet the pathogen, expands its membrane more and more. Then the pathogen is eaten by it. So the lysosomes move towards the phagosome, their membranes opened and mixt together. The enzymes fragmented the pathogen into small parts in different shapes of it and they act as antigens. The parts of pathogen are then sent on the surface of cell and displayed outside.
