This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad). The spleen also helps the body fight infection.How does the role of the spleen differ from the role of lymph nodes?Comparison and definition of spleen and lymph node: a phylogenetic analysis. Jønsson V. Thus, it is suggested that the spleen be defined as a hemopoietic organ which is able to filter blood with sinusoids. In contradistinction, a lymph node is defined as a hemopoietic organ which is able to filter lymph with sinusoids.
