The lymphatic system includes an intricate network of vessels that collect the excess tissue fluid, called lymph, and return it to the circulation (Fig. 7-1). Lymph is a clear, colorless, alkaline fluid made up mostly of water, along with some protein, salts, fats, white blood cells, and urea (a waste product of protein metabolism). Lymphatic vessels are found throughout the body alongside arteries, veins, and capillaries.
