Primary (or central) lymphoid tissues can also be referred to as the lymphoid organs. Maturation of [[Lymphocytes|lymphocytes]] and ([[Leukopoiesis#Lymphopoiesis|lymphopoiesis]]) occurs in the primary lymphoid tissues, with different tissues responsible for maturing different types of [[Lymphocytes|lymphocyte]].The primary lymphoid tissues are:
