<p>Can anyone explain how the process of immunization works when dealing with pathogens?
This is what I’ve come to so far some might be right or wrong:
Pathogen enters body and a white blood cell (leukocyte) engulfs the pathogen through phagocytosis. The white blood cell has a vacoule which lets the pathogen inside and has lysosomes that break the pathogen down. A type of lymphocyte (t cell) come into the process and and take part of the pathogen and recognize it by memory. The t cell then creates another lymphocyte known as a b cell which also memorizes the pathogen and creates antibodies which destroy it. The memory b cells memorize this type of pathogen and are ready to destroy any more that come to the body.</p>
<p>Please let me know if my explanation is right/wrong and if I made any mistakes.</p>
<p>Also what are</p>
<p>helper t-cells</p>
<p>and why do memory b cells clone themselves for what purpose?</p>
