Which of the Following is True of the B Cell

Question

Which of the following is true of the B cell?
A) Activated in response to a specific antigen
B) Engages in cell-mediated combat
C) Called a Kupffer cell when fixed within the hepatic sinusoids
D) All of the above are true.

Accepted Answer

B cells are activated in response to a specific antigen and produce antibodies, which are part of the humoral immune response. B cells do not engage in cell-mediated combat, which is the function of T cells. Kupffer cells are a type of macrophage located in the liver, and are not related to B cells.
