Multiple Choice
Which type of immune cell is primarily responsible for releasing antibodies that act against a particular foreign substance?
A
Eosinophils
B
Basophils
C
Neutrophils
D
B lymphocytes (plasma cells)
Verified step by step guidance1
Understand that antibodies are proteins specifically designed to recognize and bind to foreign substances (antigens) to neutralize or mark them for destruction.
Recall that different immune cells have distinct roles: eosinophils mainly combat parasites, basophils are involved in allergic responses, and neutrophils are key players in phagocytosis of pathogens.
Identify that B lymphocytes, upon activation by an antigen, differentiate into plasma cells, which are specialized for producing and secreting large amounts of antibodies.
Recognize that plasma cells are the effector form of B lymphocytes responsible for the humoral immune response, which involves antibody-mediated immunity.
Conclude that the immune cells primarily responsible for releasing antibodies against specific foreign substances are B lymphocytes (plasma cells).
