Functions of the Lymphatic System for Massage Therapists/Students:
Draining interstitial fluid
Protecting against invasion – immune response involving the Tand B lymphocytes and also phagocytes
Transporting dietary fats – carry lipids and lipid soluble vitamins from the gastrointestional system into the blood
Returns nutrients and proteins to the blood
Lymphatic Vessels and Lymph
Lymphatic Capillaries – close ended vessels in the spaces between the cells of the body which are slightly larger than blood capillaries. Allows interstitial fluid to flow into them but not out. The ends of the endothelial cells overlap acting as one way valves. Found throughout the body except in avascular tissue, the CNS and bone marrow. Capillaries converge into lymphatic vessels.
Components of Lymph – water, oxygen, nutrients, proteins, some fats, hormones
Lymphatic Circulation- Lymph is moved via skeletal muscle pump and the respiratory pump. Lymphatic vessels lie in the subcutaneous tissue and generally follow veins. Lymphatic vessels of the viscera generally follow arteries forming plexuses around them.
Lymphatic Vessels: (from smallest to largest)
Lymphatic trunks – named for the area of the body that they drain – lumbar, intestinal, bronchomediastinal, subclavian and jugular trunks
Right lymphatic duct – approximately 1/2 inch long, drains the right upper side of the body and empties into the subclavian vein
Thoracic (left lymphatic) duct – approximately 18 inches long. Starts as a narrowing of the cisterna chyli in front of second lumbar vertebra. Cisterna chyli receives lymph from the right and left lumbar trunks and from the intestinal trunk. All of the body that is not drained by the right duct.
Nodes are oval or bean shaped and are found around lymphatic vessels. They range from .04 inches to 1 inch in length. Found in groups scattered throughout the body. Usually a superficial set and a deep set.
Most important lymph nodes: Cervical, axillary, tracheobronchial nodes, messenteric nodes
Other lymphatic tissues:
Tonsils – pharyngeal, palatine, lingual
Spleen – phagocytosis of worn out or damaged Red Blood Cells and platelets
Thymus gland – in front of the heart
Metastisis – cancer may travel though lymphatic system
Edema- from increased permeability of capillaries from infections or drugs or damage. Increased venous pressure from cardiac problems or blood clots.

Learn Lymphatic Drainage techniques:
International Alliance of Healthcare Educators: Lymph Drainage Therapy (LDT) is an original hands-on method of lymphatic drainage developed by Bruno Chikly, MD, of France. Based on the traditional knowledge of Emil Vodder and F.P. Millard. LDT combines precise anatomical and physiological knowledge with techniques of direct listening that enable practitioners to very effectively stimulate the lymphatic flow.
