The activated B cell then goes through a process of rapid division (termed clonal expansion) where many more copies of the cell are made.
Bone marrow produces lymphocytes and monocytes and all other blood cells.
They are white blood cells called lymphocytes. There are two broad categories of lymphocytes, namely the large granular lymphocytes and the small lymphocytes, most small lymphocytes are T or B cells, and most granular lymphocytes are NK, or Natural Killer, cells.
Lymphocytes arise in red bone marrow, they then mature into T cells or B cells, when actived the mature cells attack infected cell
Undifferentiated lymphocytes are produced in the bone marrow. They then migrate to the thymus or other lymphoid tissues to mature and differentiate into T cells, B cells, or natural killer cells.
Cells are formed through the division of other cells.
Immature, undifferentiated, dividing cells, for example: White blood cells and sperm cells.
Natural Killer cells are lymphocytes (white blood cells specialised in immunity) that are cytotoxic, meaning that they produce toxins that affect other cells.
Lymphocytes are blood cells that are most closely associated with the immune system. They play a key role in identifying and fighting off foreign invaders such as bacteria, viruses, and other pathogens. There are different types of lymphocytes, including T cells, B cells, and natural killer cells that work together to defend the body against infections and diseases.
Lymphocytes are one of the five types of white blood cells (WBCs), the other four being monocytes, eosinophils, neutrophils, and basophils. Lymphocytes normally account for 25-33% of total WBCs.
cells come from other cells
hodkin's disease is distinguished from other lumphomas by the precence of large, cancerour lymphocytes known as reed-sternberg cells.
Specific immunity is primarily controlled by two types of lymphocytes: T cells and B cells. T cells are responsible for cell-mediated immunity, helping to directly kill infected cells or activate other immune cells, while B cells are involved in humoral immunity, producing antibodies that target specific pathogens. Together, these lymphocytes play a crucial role in the adaptive immune response, providing long-lasting protection against infections.
