What is Lymphatic Network?

The lymphatic network consists of the lymphatic vessels, which circulate lymph throughout the body. Lymph is a liquid which carries out exchange of gases, nutrients, and wastes between the capillaries and the cells. Lymph permeates the intercellular spaces and serves in transport to the tissues, and also in the immune system. It is formed when osmotic pressure forces interstitial fluid into the close ended lymphatic capillaries.

The lymphatic capillaries join to form open ended lymphatic vessels with one-way valves similar to those in veins. The smaller lymphatic vessels join to form lymphatic trunks, which eventually join to form the right lymphatic duct and the thoracic duct. These two large ducts empty into the large veins leading to the heart.
