Which type of cell is produced to specifically target foreign bodies that the immune system encounters?

• A. T cells
• B. B cells
• C. Leukocytes
• D. Platelets

Answer: (B)

The correct response is B, B cells, because these cells are a vital component of the adaptive immune system. B cells are specifically responsible for producing antibodies that bind to foreign antigens, such as those found on pathogens like bacteria and viruses. When a B cell encounters a foreign body, it can differentiate into a plasma cell, which secretes large quantities of antibodies tailored to recognize and neutralize that particular invader. In addition, B cells are key players in the immune memory process; after an initial encounter with a pathogen, some B cells become memory cells. These memory B cells persist in the body and enable a quicker and more effective response during future exposures to the same pathogen. This specificity for foreign bodies is what distinguishes B cells from other types of cells involved in the immune response, such as leukocytes, which are a broader category that includes various immune cells but do not specifically produce antibodies.
