 | Lymphangiogram Lymph is a clear, yellowish fluid containing white blood
cells, fats, proteins, and other substances. White blood
cells help fight infection. Lymph travels through a series
of vessels, lymph nodes (oval-shaped organs throughout the
body), and other organs known as the lymphatic system. The
lymphatic system helps recycle body fluids, produce some
white blood cells, and carries nutrients around the body.
