The lymphatic system is part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph unidirectionally towards the heart. Lymphatic organs play an important part in the immune system, having a considerable overlap with the lymphoid system. The lymphatic system has multiple interrelated functions: it is responsible for the removal of interstitial fluid from tissues, it absorbs and transports fatty acids and fats as chyle from the digestive system,and ttransports white blood cells to and from the lymph nodes into the bones.
