Lymphatic system functions
The lymphatic system has three interrelated functions. It is absorb lipids from the intestine and transport them to the blood; collect and return interstitial fluid, including plasma protein to the blood, and thus help maintain fluid balance, defend the body against disease by producing lymphocytes.
Organs of lymphatic system
Lymph organs include the bone marrow, lymph nodes, spleen, and thymus.
Diseases and other problems of the lymphatic system can cause swelling and other symptoms. Problems with the system can impair the body’s ability to fight infections.
Lymphatic system diseases
Diseases of the lymphatic system: Some common causes of swollen lymph nodes include infections, infectious mononucleosis, and cancer, e.g. Hodgkin’s and non-Hodgkin’s lymphoma, and metastasis of cancerous cells via the lymphatic system. In elephantiasis, infection of the lymphatic vessels cause a thickening of the skin and enlargement of underlying tissues, especially in the legs and genitals. It is most commonly caused by a parasitic disease known as lymphatic filariasis. Lymphangiosarcoma is a malignant soft tissue tumor (soft tissue sarcoma), whereas lymphangioma is a benign tumor occurring frequently in association with Turner syndrome. Lymphangioleiomyomatosis is a benign tumor of the smooth muscles of the lymphatics that occurs in the lungs.
