Lymphocyte
Chapter: 2
A class of leukocyte produced in a variety of lymphoid organs throughout the body that is responsible for cellular and humoral immune responses. Lymphocytes can be divided into two main classes, T lymphocytes and B lymphocytes (see separately). Lymphocytes are often seen at sites of chronic inflammation. They produce many secretory products (lymphokines) that modulate the functional activities of a wide variety of cell types.
