Final answer:
B-cells are a type of leukocyte called lymphocytes. They produce antibodies and play a crucial role in the immune response.
Step-by-step explanation:
B-cells are a type of leukocyte called lymphocytes.
Lymphocytes are a type of white blood cell that play a crucial role in the immune system. B-cells are responsible for producing antibodies, which are proteins that help the body identify and neutralize foreign substances, such as bacteria or viruses.
When B-cells encounter these foreign substances, they can differentiate into plasma cells, which produce and secrete large amounts of antibodies. The antibodies then bind to the foreign substances and mark them for destruction by other immune cells. This process is an important part of the adaptive immune response and helps the body defend against infections.
Overall, B-cells are an essential component of the immune system and play a vital role in protecting the body against pathogens and foreign substances.
