  1. The Lymphatic System 3 Functions of the Lymphatic System • Your body's excess tissue fluid is removed by the lymphatic system. • Lymph is tissue fluid that diffuses into the lymphatic capillaries.

  2. Your lymphatic system, carries lymph through a network of lymph capillaries and larger lymph vessels. • The lymphatic system runs along side of the circulatory system vessels.

  3. The Lymphatic System 3 Functions of the Lymphatic System • The movement of lymph depends on the contraction of smooth muscles in lymph vessels and skeletal muscles. • If the lymphatic system is not working properly, severe swelling occurs because the tissue fluid cannot get back to the blood.

  4. The Lymphatic System 3 Functions of the Lymphatic System • Lymphocytesare a type of white blood cell found in lymph. • Lymphocytes help your body defend itself against disease causing organisms.

  5. The Lymphatic System 3 Lymphatic Organs • Lymph nodes are bean-shaped organs of varying sizes found throughout the body. • Lymph nodesfilter out microorganisms and foreign materials that have been taken up by lymphocytes.

  6. The Lymphatic System 3 Lymphatic Organs • When your body fights an infection, lymphocytes fill the lymph nodes. • During an infection the lymph nodes become warm, reddened, and tender to the touch.

  7. The Lymphatic System 3 Lymphatic Organs • Besides lymph nodes, the tonsils, the thymus, and the spleen are important lymphatic organs. • Tonsils protect you from harmful microorganisms.

  8. The Lymphatic System 3 Lymphatic Organs • Your thymusmakes lymphocytes that travel to other lymph organs. • The spleenfilters the blood by removing worn out and damaged red blood cells.

  9. The Lymphatic System 3 A Disease of the Lymphatic System • HIV is a deadly virus. • When HIV enters a person's body, it attacks and destroys lymphocytes called helper T cells that help make antibodies to fight infections. • HIV affects a person's immunity to some diseases. • Usually, the person dies from these diseases, not from the HIV infection.
