Among the last line of defenses against prolonged exposure to an extracellular pathogen is ________.
A) lysozyme production
B) phagocytosis by neutrophils
C) antibody production by plasma cells
D) histamine release by basophils
E) mast cell activation

Question

Quizplus · Accepted Answer

Antibody production by plasma cells is a key defense mechanism against extracellular pathogens. Antibodies can neutralize the pathogen by binding to its surface and preventing it from infecting host cells. Additionally, antibodies can also recruit other immune cells to the site, leading to the destruction of the pathogen. Lysozyme production and phagocytosis by neutrophils are early defense mechanisms against pathogens, while histamine release and mast cell activation are associated with allergies and inflammation.
