Question

B lymphocytes
A)differentiate into antibody-producing cells.
B)originate in the spleen.
C)are activated by neutrophils in an immune response.
D)mature in the thymus.
E)function in cell-mediated immunity.

Accepted Answer

B lymphocytes differentiate into antibody-producing cells, which are important in humoral immunity.

Answer: B 
 While some B lymphocytes may pass through the spleen, they actually originate from stem cells in the bone marrow.

Answer: C 
 Neutrophils are part of the innate immune response and do not activate B lymphocytes, which are part of the adaptive immune response.

Answer: D 
 B lymphocytes mature in the bone marrow, not the thymus.

Answer: E 
 B lymphocytes do not function in cell-mediated immunity. Instead, they are part of the humoral immune response, producing antibodies to recognize and bind to specific antigens.
