Final answer:
Passive immunity involves the transfer of antibodies from one individual to another, providing temporary immune protection without the creation of immunological memory.
Step-by-step explanation:
The transfer of immunoglobulins or antibodies from an immune individual to another is involved in passive immunity. This form of immunity provides temporary protection and can be acquired naturally or artificially. Naturally acquired passive immunity occurs, for example, when a mother transfers IgG to the fetus through the placenta and IgA through breast milk after birth. Artificially, it can be achieved by administering immunoglobulins from a previously exposed individual to someone who needs immediate protection against a specific pathogen. This treatment, however, does not prompt the development of immunological memory, meaning that once the transferred antibodies degrade, the protection is lost.
