ANATOMY

Detailed explanation-1: -B-cells and T-cells are the two main types of lymphocytes. There are primary and secondary organs involved in the complex development of lymphocytes, but in most cases, B-and T-lymphocytes are generated in bone marrow and in the thymus.

Detailed explanation-2: -There are several types of T cells; the most common and well-known are the CD4+ T cells (helper T cells) and CD8+ T Cells (cytotoxic T cells, or killer T cells).

Detailed explanation-3: -The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies, and T lymphocytes help kill tumor cells and help control immune responses. A lymphocyte is a type of white blood cell.

Detailed explanation-4: -Definition. A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.

Detailed explanation-5: -Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
