There are series of one way valves that keep the fluid moving in one direction. Inside the lymph nodes are white blood cells, also called lymphocytes. As lymph passes through the lymph nodes, the white blood cells attack any bacteria or viruses found in the lymph. How Does The Lymphatic System Support The Body? Extracellular fluid in the lymphatic system is known as lymph. The lymph system does not have a built-in pump to move lymph fluid through the body the way the cardiovascular system does. The thoracic duct receives lymph from the rest of the body and empties it into the left subclavian vein. The nodes act as a filter. Deep Breathing. These lymph vessels connect to a group of lymph nodes. Your lymph nodes are connected to one another by lymph vessels (tubes that run through your body like veins). The lymph system is similar to the venous system in the body. What happens in the lymph nodes as lymph flows through them. Of the nearly 800 lymph nodes in the human body… Along the way, the lymph passes through a series of lymph nodes (small, bean-shaped organs), which filter debris and foreign invaders, such as bacteria and virus, from the lymph. Plasma and mature T cells are added. Lymph contains disease-fighting cells called lymphocytes, which are supplied by the lymphatic system. Lymphoid organs and lymph nodes filter lymph fluid and remove bacteria, viruses, and other toxins from the body. Because the lymphatic system is such an integral part of a healthy immune system and keeping your body free of waste and even cancer, it is imperative you assure the lymph continues to move efficiently throughout your body. Muscle contractions and pressure changes caused by breathing. Some of the key areas in which the lymphatic system supports the body are the following: Immune System: The lymphatic system is best known for its defense against infection and disease. Lymph slowly accumulates in lyphatic vessels from blind lymphatic capillaries. Lymph ultimately drains in subclavian veins of either side. Lymphatic system, network of vessels and other tissues, including the tonsils, spleen, and thymus, that maintains fluid balance and fights infection. There are two major drainage vessels: right lymphatic duct and left thoracic duct for slowly but continuously drain the lymph in venous system. During exercise the lymphatic pump becomes very active. Deep breathing promotes lymph flow. What makes the lymph fluid move through the body? 11. There are several ways to do this. Keep Moving. 1. If cancer cells break away from a tumor, they can attach to the nearby lymph nodes. They trap or destroy anything harmful that the body does not need. Your lungs pump your lymphatic fluid. Reticular fibers filter out debris. Lymph relies on your bodily movements to move through your body. Stretching the arms to both sides then move your ARMS up while breathing in (through the nose) and at the same time make circles with your HANDS (deep breath from the lungs, not the stomach, the expansion of the lungs squeezes the thoracic duct and creates more flow). Lymph nodes are located at intervals along the lymphatic system. Exercise can increase lymph flow ten to thirty fold. 2) movement of the body 3) pressure changes in the thorax during respiration 4) compression of tissues by objects of the body 5) arterial pulsations During periods of rest, lymph is sluggish. Signs of Lymphatic Congestion. Several afferent lymph vessels bring in lymph, which percolates through the substance of the lymph node, and is then drained out by an efferent lymph vessel. Instead, it is squeezed through the body by muscle contractions and other movements. If the lymphatic system didn’t drain excess fluid from the tissues, the lymph fluid would build up in the body and cause swelling. Lymph fluid normally flows through a network of lymph vessels. Filters lymph. They carry lymph fluid -- a clear, watery liquid that passes through the nodes. Foreign substances are destroyed. Thoracic duct drains 75% of lymph in left subclavian vein.
