Bone marrow is a significant source of antibodies as a large population of antibody-producing cells ([[B cell differentiation#Plasma cells|plasma cells]]) reside there. [[Macrophages|Macrophages]] and [[T cell differentiation#Dendritic Cells|dendritic cells]] in the marrow remove foreign substance from the blood, a process which also occurs in the [[Lymph Nodes - Anatomy & Physiology|lymph nodes]], [[Spleen - Anatomy & Physiology|spleen]] and [[Liver - Anatomy & Physiogy#Functions|liver]].
