Verified step by step guidance

Understand the different types of immunity: Active immunity involves the body's direct response to an unknown pathogen, while passive immunity involves receiving antibodies from an external source.

Recognize that passive immunity is acquired through the transfer of antibodies from another individual or species, such as through breast milk or antibody-containing blood products.

Differentiate between passive and active immunity: Active immunity requires the immune system to produce its own antibodies, often through vaccination or exposure to the disease.

Consider cell-mediated immunity, which involves T-cells and does not directly involve antibodies, making it distinct from passive immunity.

Identify innate immunity as the body's first line of defense, which is non-specific and not acquired through external antibodies, unlike passive immunity.
