Lymph is a clear fluid, much similar to blood plasma. It is also called tissue fluid in the lymphatic vessels. Lymph contains macrophages which phagotize foreign materials such as bacteria, viruses and cancer cells. Lymph travels throughout the body looking for foreign objects until it gets emptied into the subclavian veins where the flow of the blood pulls the lymph in it.
