Lymphatic System

A network of organs, nodes, ducts, and vessels that produce and transport lymph from the body’s tissues to the bloodstream. The lymphatic system helps to maintain fluid balance in the tissues and blood; to supply nutrients, oxygen, and hormones to cells; to transport fats, proteins, and white blood cells to the blood; and to fight infections and filter out foreign organisms and waste products.
