Verified step by step guidance

1. Begin by understanding the different types of immunity: Humoral immunity, Passive immunity, Cell-mediated immunity, and Innate immunity.
2. Humoral immunity involves the action of B cells and the production of antibodies to neutralize pathogens.
3. Passive immunity refers to the temporary immunity gained through the transfer of antibodies from another source, such as maternal antibodies.
4. Innate immunity is the body's first line of defense, involving physical barriers and non-specific immune responses.
5. Cell-mediated immunity primarily involves T cells, which are responsible for directly attacking infected cells and coordinating the immune response.
