Bone marrow comes in two types: red marrow and yellow marrow.
The red bone marrow also warehouses plasma cells, which are integral to immune function (not related to the PLASMA that forms the fluid base of blood). The red bone marrow is the location where B-cell lymphocytes, which migrate to the marrow from the LYMPH tissues that produce them, come to maturity. Yellow bone marrow produces a few leukocytes in adulthood though primarily functions as a reserve resource for new blood cell production when the red bone marrow cannot meet the bodyâs needs.
