The lymphatic system is a multi-functional body system. Its roles include transportation of lymph and combating infection.
The components of the lymphatic system include lymphatic vessels, lymph nodes, and lymphatic organs.
Lymphatic vessels form an extensive network of thin-walled vessels that transport lymph around the body, eventually emptying it into the venous system. These vessels contain numerous valves and have a beaded appearance, bulging between adjacent valves when filled with lymph.
Lymph nodes are small masses of lymphatic tissue situated along the course of the superficial and deep lymphatic vessels. Their function is to filter lymph as it passes through the lymphatic system and route to the venous system.
Lymphatic organs are structures that produce lymphocytes, and include the spleen and the thymus gland. Lymphocytes are white blood cells which circulate in the bloodstream and lymphatic system. They are concentrated in lymph nodes. They are components of the immune system and have a role in combating infection.
