B cell
This term is a specialized biological designation used primarily in immunology and medical contexts. It refers to a specific lineage of white blood cells that originate in the bone marrow, which is the origin of the "B" in the name. These cells are the primary drivers of humoral immunity, meaning they secrete antibodies into the blood and lymph to target foreign invaders.
In professional scientific writing, the term is typically used in the singular when discussing the cell's function or in the plural when discussing populations or concentrations within a sample. It is almost always paired with "T cell" when describing the broader adaptive immune system, as the two work in tandem to identify and eliminate pathogens.
