Leucocytes
Leucocytes or leukocytes, colloquially known as white blood cells (WBCs), are clear, colorless cells that circulate in the blood and lymph and are integral part of the immune system.[1]
There are two lymphoid tissue types: Primary Lymphoid tissues, comprising the bone marrow and thymus where leucocytes are synthesized[2]
Secondary lymphoid tissues, comprising the spleen, lymph nodes and mucosa associated lymphoid tissues (MALT)[2]
Secondary lymphoid tissues contain the mature leucocytes that react to infection, triggering an immune response[2].
There are multiple forms of leucocyte.
