Is there a connection between lymph and blood?

Yes! Lymph is an important part of the circulatory system. It helps maintain the fluid balance in blood by carrying fluid from extracellular environments into the blood stream (such as water, proteins, and other substances). Lymph also plays a primary role in one's immunity because it is rich in white blood cells (lymph nodes are also the sight for lymphocyte production, which remove microorganisms and other foreign materials by utilization of phagocytosis). The two main ducts that drain lymph into the bloodstream include:

1.) right lymphatic duct- drains lymph from upper right portion of body into the right subclavian vein.

2.) thoracic duct- drains lymph from the rest of the body to the left subclavian vein (just before it becomes the superior vena cava).
