Question

Quizplus · Accepted Answer

Macrophages are specialized cells that engulf and digest foreign pathogens. They then present the antigens (parts of the pathogen) on their surface to activate other cells of the immune system to mount a response. Red blood cells do not have a nucleus and are not involved in immune responses. Antibodies are proteins produced by B cells and do not have the ability to engulf pathogens. Vaccines are not cells, but rather weakened or inactivated pathogens or parts of pathogens used to stimulate an immune response.
