Multiple Choice
In B cell development, antibodies are primarily secreted by which type of cell?

C
Neutrophil
D
Plasma cell
Verified step by step guidance1
Understand the role of B cells in the immune system: B cells are a type of white blood cell responsible for producing antibodies, which help identify and neutralize pathogens like bacteria and viruses.
Identify the different stages of B cell development: Naive B cells are mature B cells that have not yet encountered an antigen, while plasma cells are differentiated B cells specialized in antibody secretion.
Recognize that CD8+ cytotoxic T cells are a different type of immune cell involved in killing infected cells, not antibody production.
Note that neutrophils are another type of immune cell primarily involved in phagocytosis and inflammation, not antibody secretion.
Conclude that plasma cells are the terminally differentiated B cells that actively secrete large amounts of antibodies during an immune response.
