What cells are responsible for the production of antibodies?

The production of antibodies is primarily the function of B lymphocytes. These specialized white blood cells, also known as B cells, are a crucial component of the adaptive immune system. When B lymphocytes encounter a pathogen or foreign substance, they can differentiate into plasma cells, which are the cells that produce and secrete antibodies. These antibodies are proteins that specifically target and neutralize pathogens such as bacteria and viruses, aiding in the body’s defense mechanism.

This process is essential for establishing immunity, as antibodies can provide long-lasting protection by recognizing previously encountered pathogens. Thus, B lymphocytes play a vital role in both immediate and long-term immune responses, making them the correct answer regarding which cells are responsible for antibody production.
