How do plasma cells form, and how do they help fight pathogens. Answers. Plasma cells, they are also called plasma B cells, or effector B cells, are white blood cells that secrete large volumes of antibodies. They are transported by the blood plasma and the lymphatic system. Plasma cells originate in the bone marrow; B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell.
Facts about plasma. Plasma is the largest component of your blood, making up about 55 percent of its overall content. When isolated on its own, blood plasma is a light yellow liquid, similar to the color of straw. Along with water, plasma carries salts and enzymes. The primary purpose of plasma is to transport nutrients, hormones, and proteins to the parts of the body that need it. Cells also deposit their waste products into the plasma, and the plasma in turn helps remove this waste from the body.
