Lymphatic vessel

Lymphatic Vessel

A Lymphatic Vessel is a component of the Lymphatic System, which is an integral part of the Immune System. The lymphatic vessels are responsible for the transportation of Lymph, a clear fluid containing White Blood Cells, throughout the body.

Structure

Lymphatic vessels are similar in structure to Blood Vessels, but they are thinner and have more valves. These valves prevent the backflow of lymph, ensuring it moves in one direction - towards the Lymph Nodes. The smallest lymphatic vessels are the Lymph Capillaries, which absorb the lymph from the interstitial spaces in the body tissues.

Function

The primary function of the lymphatic vessels is to transport lymph, which is rich in proteins and white blood cells, throughout the body. This helps in the removal of toxins, waste and other unwanted materials. The lymphatic vessels also play a crucial role in the body's immune response, as they transport infection-fighting cells called Lymphocytes.

Clinical Significance

Diseases and conditions affecting the lymphatic vessels can have serious health implications. Lymphedema, a condition characterized by swelling in the arms and legs, is caused by a blockage in the lymphatic system. Lymphangitis, an inflammation of the lymphatic vessels, usually occurs as a complication of a bacterial infection.
