Anatomy and Physiology • Lymph vessels, ducts, and nodes • Protects body from infection by filtering bacterial and nonbacterial products • Prevents waste products from entering circulatory system • Dependent on vascular system • Lymph is clear fluid Copyright © 2010 Delmar, Cengage Learning.

Anatomy and Physiology • Two divisions of lymph system: – Right lymphatic duct drains lymph from head, upper torso, and right arm – Left lymphatic duct • Also known as thoracic duct • Rest of body drains through this duct – Organs related to lymph system: • Tonsils, thymus gland, and spleen Copyright © 2010 Delmar, Cengage Learning.

Common Signs and Symptoms • Enlarged lymph glands or nodes, fever, fatigue, and weight loss • Most diseases of lymphatic system related to diseases of other systems Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Diagnostic Tests • Complete blood count (CBC) with differential • Lymphangiography – X-ray of lymph system after dye injection • MRI • CAT scan • Biopsy of lymph nodes Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Common Diseases of the Lymphatic System • Lymphangitis – Swelling of lymph vessels due to inflammation caused by strep infections following trauma – Characterized by red streak at bacterial entry extending to area of lymph node Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Common Diseases of the Lymphatic System • Lymphedema – Abnormal collection of lymph fluid in extremities – Possible causes: • • Surgery or radiation treatments Pregnancy Burns Trauma Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Common Diseases of the Lymphatic System • Lymphedema – Treatment: • Antibiotics • Compression therapy • Surgical intervention depending on cause Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Common Diseases of the Lymphatic System • Lymphoma – Neoplasms affecting lymphoid tissue – Affects normal lymphocyte production leading to impaired immunity – Most common type of blood cancer in United States Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Rare Diseases • Kawasaki disease – Symptoms: • • Rash similar to scarlet fever Edema of feet and hands Lethargy Congestion – Supportive treatment Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.

Effects of Aging • Decreased ability to produce antibodies – Thus, more prone to infections • Increased susceptibility to autoimmune disorders • Impairment of vascular system also impacts function Copyright © 2010 Delmar, Cengage Learning. ALL RIGHTS RESERVED.
