The lymphatic system is the other transport system of human body (like blood transport system). It is a complex network of lymphoid organs, lymph nodes, lymph ducts, lymph capillaries and lymph vessels that produce and transport lymph fluid from tissues to the circulatory system.
Lymph is a circulatory fluid like blood. It runs in the lymph capillaries. It is colourless and contains most of the ingredients similar to blood. It does not contain RBC. Lymph mainly contains WBCs and plays an important role in fighting infections. It also contains most of the protiens present in blood. Lymph finally joins into the blood capillaries.
Lymph is collected from tissues in most parts of the body and returned to the blood via the lymphatic system.
Lymph organs include the bone marrow, lymph nodes, spleen, and thymus. Precursor cells in the bone marrow produce lymphocytes. B-lymphocytes (B-cells) mature in the bone marrow. T-lymphocytes (T-cells) mature in the thymus gland. Human lymph nodes are bean-shaped.They may become enlarged due to a tumor or infection. WBCs are present in the lymph nodes. Lymph nodes are filters of lymph.
