![]() Peyer’s patches are small masses of lymphatic tissue found throughout the ileum region of the small intestine. Also known as aggregated lymphoid nodules, they form.Start studying Chapter 24 Digestive System. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Diagrams, Function And Role, Immune Response, Diseases Of Lymph System: Edema. Interrelationships: What Other Systems Does It Work With? The lymphatic system links to: Circulatory System: The lymphatic system transports excess waste and toxins that the circulatory system cannot cope with, away from the cells and tissues. It also works closely with the circulatory system to strengthen the body's immunity. Digestive System: Lymphatic vessels in the small intestines (inside the lacteal of the ileum) help with the absorption of fats during digestion. These are then transported around the body in the circulatory system and distributed to cells to be used as energy. Muscular System: Lactic acid formed when over- exercising muscles, or from tension and general fatigue in the muscular system, is drained away in the lymphatic system. How Does Lymph Move? The lymphatic system has no pump to make the lymph fluid move. Instead fluid is circulated as a side effect of muscle movement (physical activity) and heartbeats. When the muscles in our body contract they squeeze (compress) the lymph vessels so that lymph fluid is moved on. Valves inside the vessels (which only open in one direction) ensure that the fluid always flows in the right direction. What Is the Connection Between Blood And Lymph? The lymphatic system is a subsidiary circulation, helping the blood circulation to carry out its functions. It removes excess fluid from tissues and carries large particles that cannot pass through the smaller pores of the blood capillaries. Lymph nodes and the spleen filter lymph (the name of the fluid in the lymphatic system) and take out the waste materials it contains as well as producing antibodies and lymphocytes which are added to the lymph to be transported to the blood. Diseases And Disorders (Pathologies)When you have an infection (such as a cold), the lymph nodes (sometime referred to as 'glands') in your neck or groin or under your arm may swell. This is a sign that white blood cells (lymphocytes) are fighting germs. If the infection is severe, the vessels leading from the nodes can become inflamed (lymphangitis). The following is a list of other common, and less common diseases and disorders that affect the lymph system: Edema/water retention: Temporary swelling due to excess fluid in the body’s tissues. Typically affects the legs, ankles, feet and hands but can involve your whole body. Water pills (diuretics) can help your body excrete fluids. Lymphedema: Chronic long- term edema which may result from cancer surgery, radiotherapy, trauma, allergic reaction, lack of movement or parasites (worms blocking a lymphatic vessel). Hodgkin's disease: Cancer of the lymphatic tissue. Cancer: The fastest way for cancer to spread throughout the body is via the lymphatic system. If a cancer tumor (lump) invades a nearby lymph vessel, cancer cells from the tumor can break off and enter the vessel (known as metastasis). They may become lodged in nearby lymph nodes when they grow into a secondary tumor. For example, with breast cancer, cells from the breast lump can spread to the lymph nodes in the armpit. In advanced stages, cancer cells travel through the lymph to other parts of the body. See stages of breast cancer. Cellulite: Lumpy deposits of body fat (described as orange- peel appearance) especially on women's thighs. See, what is the best treatment for cellulite? Infectious mononucleosis (glandular fever): A viral infection caused by the Epstein- Barr virus. It causes swollen lymph nodes (usually the neck), a sore throat and extreme tiredness. Those between the ages of 1. The illness usually passes without serious problems. It’s not highly contagious. The virus can be transported via air droplets or transmitted by kissing. Lymphadenitis: The inflammation of lymph nodes. Non- Hodgkin lymphoma: A type of lymphoma, a cancer in the lymphatic system; causes the cells in the lymphatic system to abnormally reproduce, eventually causing tumors to grow. Hashimoto's thyroiditis (chronic lymphocytic thyroiditis): A type of thyroid disease. Hashimoto's is an autoimmune disease where the body's own T- cells attack the cells of the thyroid. Lymphoma: Is a type of cancer that originates in lymphocytes of the immune system. They often first form in lymph nodes where they cause a tumor to grow (presenting as an enlargement of the node). Systemic lupus erythematosus (SLE) or just lupus: Lupus is an autoimmune disease that affects connective tissues in the body (including the skin, joints, brain, kidneys). Produces new lymphocytes (white blood cells).
