Question

Quizplus · Accepted Answer

Passive immunity involves the introduction of antibodies into an organism from another organism, rather than the organism's own immune system producing the antibodies. This can occur naturally, such as antibodies passed from mother to fetus during pregnancy, or artificially through injection of purified antibodies. Active immunity, on the other hand, occurs when an organism's own immune system produces antibodies in response to being exposed to a foreign substance. Primary immunity and secondary immunity are not terms commonly used to describe types of immunity. Tertiary immunity is not a recognized term.
