Lymphatic fluid moves within the body through a system of capillaries, vessels, nodes and ducts. Through simple body movements and the action of breathing the fluid is moved along by the contraction of the skeletal muscles. The fluid moves in one direction towards the heart. Lymph capillaries merge to form larger vessels. These vessels have thin walls with a smooth layer of muscle which help to pump the lymph along. The lymph capillaries run alongside the blood vessels, tissue fluid passes out of the spaces between cells and through the walls of the lymph capillaries. These then merge into larger vessels. Eventually the fluid enters the thoracic duct and empties into the blood circulatory system before the
B. Given that lymph vessels carry under very low pressure, they require assistance in moving lymph, especially vessels below the level of the heart which must move lymph upwards against gravity. The 2 mechanisms which
Once the blood cell gets to the superior vena cava it goes through the right atrium and the right ventricle, then through the pulmonary artery and into the lungs.
The right ventricle fills up tricuspid valve closes right ventricle contracts pulmonary valve opens the blood flows into the pulmonary artery pulmonary valve closes pulmonary artery splits into two vessels each going to the lungs.
movement of water in tissues and maintain the fluidity of mucus and other secretions [3].
Lymphatic massage was introduced in the 1930s by Danish physiotherapists Dr. Emil Vodder and his wife (Benjamin, 2010). His wife Astrid Vodder practiced naturopath. Emil Vodder studied at the University of Copenhagen for biology, botany, and mineralogy, later began showing interest in the physical medicine along with the lymphatic system. Vodder knew many scientists who had studied the mysterious “clear water” centuries ago, scientist such as Gaspare Aselli (1581–1626) who discovered the lacteal vessels in the lymphatic system, Jean Pecquet (1622-1674) described the cisterna chyli and the thoracic duct leading to the venous arch (Wittlinger, 2004). Olaus Rudbeck discovered the lymph vessels of the colon and rectum and confirmed that these vessels lead to the cisterna chyli as Aselli had described already. Rudbeck was the first who discovered that the lymph from the tissue runs into lymph vessels and to the thoracic duct back to the blood circulation. In the 18th century it was discovered that the whole body contained lymph vessels and that the task of the lymph vessel system is to absorb tissue liquid. Vodder and his wife moved to Paris, France in 1933 to practice the modality on his patients (Wittlinger, 2004). The concept of lymph drainage by massage therapy is similar to opening a valve of a tube filled with water and allowing the water to flow into another tube to release pressure and alleviate build up in the lymph nodes.

The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids, appendix and clumps of tissue in the small bowel. A function of the lymphatic system is to nurture and mature the B and T-lymphocytes (white blood cells vital to immune function). Cancerous changes can take place
The lymphatic system is a series of glands found throughout the body, this system is required so cells that a person’s immune system needs can travel around the body.
The purpose of this exercise is to learn about the lymphatic system and how it works and helps the human body. Why we need it and the components associated with the lymphatic system.
The organs that make up the lymphatic and immune system are the tonsils, spleen, thymus gland, lymph nodes, and lymphatic vessels. White blood cells (leukocytes), red blood cells (erythrocytes), plasma, and platelets (thrombocytes) make up the blood. Lymphocytes are leukocytes (white blood cells) that help the body fight off diseases. Two types of lymphocytes are B cells and T cells. Lymphocytes recognize antigens, or foreign substances/matter, in the body. Lymphocytes are a classification of agranulocytes, or cells (-cytes) without (a-) granules (granul/o) in the cytoplasm. B cells are created from stem cells, which are located in the bone marrow. B cells respond to antigens by becoming plasma cells. These plasma cells then create antibodies. Memory B cells produce a stronger response with the next exposure to the antigen. B cells fight off infection and bacteria while T cells defend against viruses and cancer cells. A hormone created by the thymus gland called thymosin changes lymphocytes into T cells. The thymus gland is active when you are a child and slowly shrinks, as you get older. T cells bind to the antigens on the cells and directly attack them. T cells secrete lymphokines that increase T cell production and directly kill cells with antigens. There are three types of T cells: cytotoxic T cells, helper T cells, and memory T cells.
A lymphangiogram is a procedure to examine your lymphatic system. Your lymphatic system consists of lymph vessels and your lymph nodes. In this procedure, dye is injected through a long, thin tube (catheter). X-rays are then taken. The X-rays will show if there is a blockage or problem, such as a tumor.
The lymph Nodes swell when a problem has occurred such as an infection, or injury and white blood cells group to an area to heal the infected area. So the next thing to do is to take a bronchoscope and insert it in the nose or mouth then pushed in the lungs where the doctor
Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.
Without it, our bodies would blow up like balls, overpowering our cells with bad fluid. The lymphatic systems impact is extensive to the point that many don't comprehend that minor a throbbing or light pain, low vitality or no defense to colds and flu may be a direct result of a lazy lymphatic system and a bad immunity protection. blood plasma spills into tissues through the thin layers of walls of the vessels. The part of blood plasma that departs from the blood circulation is called interstitial or extracellular liquid, and it contains oxygen, glucose, amino acids, and different supplements required by tissue cells. Albeit the greater part of this liquid leaks quickly over into the circulation system, a piece of it is abandoned. The lymphatic system eliminates this liquid. A lymphatic obstacle is a blockage in the lymphatic structure. The lymphatic system includes lymph nodes and vessels that vacant fluids out of your body's
The lymphatic system works in three ways. It helps to control the balance of the body’s fluids by draining and cleansing fluid that seeps from the circulatory system during normal cardiovascular circulation. As fluid leaves the circulatory system it enters the tissue cells and whilst the majority of it diffuses back into the vessels of the circulatory system, the remainder enters the open ends of the lymph vessels. The lymphatic system also works with the villi in the digestive system to help deliver fats and absorbed nutrients in the digested food we eat, back to the circulatory system. This fluid is not called
A.5 Lymphatic system consists of lymph,lymph vessels,lymphatic capillaries and lymphatic nodes.Lymph is another type of fluid which is also involved in transportation.Some amount of plasma, proteins and blood cells,escape into the intercellular spaces through the pores present in the wall of capillaries,form lymph.Lymph is colorless and contains less proteins as compared to that in the blood.
