    Understanding the lymphatic system

    The lymphatic system

    The lymphatic system has a really complex structure including several hundred of lymph nodes, lymph vessels and capillaries spread throughout the body. The lymphatic system is closely associated with the blood circulation system.The lymph vessels return excess fluid collected from all over the body back into the blood circulation. This fluid is forced through the lymph nodes and filtered. Harmful organisms are trapped and destroyed by specialized white blood cells found in these nodes. Every day about two liters of lymph fluid flow into the blood circulation.

    Understanding the lymphatic system

    The three main functions of the lymphatic system


    Fighting infection

    • The lymphatic system transports a watery, clear fluid full of lymphocytes. Lymphocytes are infection-fighting cells. The colorless fluid is known as lymph. 


    Draining excess fluid

    • As the blood circulates through the body's tissues, it leaves behind waste products such as proteins and fluids. Excess fluid is drained through capillaries and into the lymphatic system where it is filtered and returned to the blood. 


    Lipid (fat) absorption

    • The lymphatic system also absorbs lipids from the intestine and transports them to the blood.
