Lymphatic system is the tissues and organs that produce, store and transport white blood cells that fight infections and other diseases. This system includes bone marrow, spleen, thymus, lymph nodes and lymphatic vesselsnetwork of thin tubes carrying lymph and white blood cells. The lymphatic vessels ramify, like the blood vessels, into all the tissues of the body.

 Lymph travels around the body through a network of lymph vessels in much the same way that blood travels around the body through the blood vessels. Whereas the blood carries nutrients and other substances into our tissues, the lymph vessels drain fluid from the tissues and transport it to the lymph nodes.

These small ovoid or kidney-shaped  masses of tissue filter out and destroy bacteria and other harmful substances. The bigger lymph vessels then carry the cleaned fluid back to the vein called the superior vena cava, where it enters the blood stream.  The lymph or lymphatic system is a important part of our body’s system to defend us against infections.
