Question

Quizplus · Accepted Answer

Passive acquired immunity is the type of immunity gained from receiving antibodies from another source, such as a mother to fetus across the placenta. This is in contrast to active acquired immunity, which is gained through exposure to pathogens and the subsequent development of one's own antibodies. Natural immunity refers to immunity gained through natural exposure to pathogens or antigens, while innate immunity is the body's initial, non-specific response to any potential invader.
