Lymph

Lymph is a clear, colorless fluid that is part of the lymphatic system in the body. It is primarily composed of white blood cells that are crucial in fighting infections, along with a liquid called lymph plasma. Lymph is transported throughout the body via lymph vessels.

Composition

Lymph is made up of a clear, watery fluid known as lymph plasma, and white blood cells, particularly lymphocytes. These lymphocytes play a key role in the body's immune response. The lymph plasma is similar to blood plasma, but contains fewer proteins.

Function

The primary function of lymph is to transport infection-fighting white blood cells throughout the body. It also serves to remove waste products from body tissues. Lymph is transported through the body via a network of lymph vessels and lymph nodes, which filter the lymph and remove harmful substances.

Lymphatic System

The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. It is primarily made up of lymphatic vessels, which are similar to the veins and capillaries of the circulatory system. The lymphatic system also includes a number of lymph nodes, which act as filters for harmful substances.

Disorders

There are several disorders that can affect the lymph or the lymphatic system, including lymphedema, which is swelling caused by a blockage in the lymphatic system, and lymphoma, which is a type of cancer that originates in the lymphatic system.
