Want to know one of health careâs dirty little secrets? While we know how much the country spends on care each year, we have little understanding of what it actually costs to provide care.

The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
Lymph is a fluid which bathes all the cells of the body. It is also called ICF (Intercellular fluid). This is made up of mostly fluid that escapes from the blood through the walls of the capillaries. Tiny, lymphatic capillaries are found in all tissues of the body. These join to form lymph vessels which are thin walled vessels that also contain valves to prevent backflow. Eventually, all lymph returns to the circulatory system through various ducts that empty into large veins below the neck. In this way, fluid that is lost through the capillary is returned to the blood. At intervals along the lymph vessels, there are bead-like enlargements called lymph nodes.
