Lymphatic system
The lymphatic system is one of the organs of the body, which consists of a network responsible for the discharge of body fluids to maintain its balance, and is responsible for the fight against infection. The lymphatic system consists of spleen, lymphatic vessels and lymph nodes distributed throughout the body’s lymphatic vessels. The lymphatic system contains a transparent water-like fluid made up of proteins : Proteins, salts, Glucose, Urea, and other substances, called lymph fluid.
Lymph nodes and their synthesis
Lymph nodes – also called lymph nodes – are made up of nodes and small glands distributed throughout the body in the form of cluster clusters. There are about 600 lymph nodes spread throughout lymphatic vessels in the body. The lymph nodes consist of two parts: the cortex, which contains lymphocytes, and consists mainly of B-lymphocytes, which mature fully in the bone marrow (in English) : Bone Marrow, T-lymphocytes, which complement their maturation outside the bone marrow. Medulla is the second part of the lymphatic glands. In addition to the above, it is important to know that the lymph nodes also contain a group of pharyngeal cells (Macrophages). Lymph nodes also surround the connective tissue.
Function of lymph nodes
The process of filtering the lymphatic fluid from the body organs surrounding the lymph glands and remove the harmful substances and remnants from it and then return to blood (blood:) of the most important functions of the lymph nodes, as these lymph nodes immune system (Immune System) The lymphatic fluid enters the lymph nodes where the white blood cells of the glands attack the foreign bodies that are carried in the lymphatic fluid, such as the bacteria, and then the liquid that is filtered returns to the bloodstream. Thus, removing the bacteria from the current Moi has been made. These lymph nodes are distributed in different parts of the body. Examples include neck area, armpits, groin in the thigh, between lungs (Lungs), around the canal Gut. For example, the lymph glands in the elbow area and the lymphatic armpits come from the hand, fingers, and arm. The lymph nodes behind the knee and in the inguinal region filter lymph fluid from the thigh, foot, and toes. The next lymphoid of the face, head, and scalp (scalp) is filtered in the lymph glands behind the head, behind the ears, and on both sides of the neck.
Inflammation of lymph nodes and swelling
Lymph nodes may be bloated and swollen, as they grow to the size of a bean, or even larger, and become painful. Its swelling and swelling indicate that something is abnormal somewhere in the body, and the symptoms depend in detail on the cause of the swelling, and the location of the swelling may help to diagnose and know the cause of the swelling. Causes of swelling and enlargement of the lymph glands include:
- Infection: Infection is one of the most common causes of lymphoma, especially a viral infection. And viral infections that cause blurred lymph glands, common cold, Strep Throat, measles, ear infections, infections and tooth abscesses, Infected and Abscessed Tooth), skin infections and wounds such as cellulitis, human immunodeficiency virus (HIV), and mononucleosis, a viral infection transmitted Saliva and Saliva Fever, inflammation of the throat, swelling of the spleen. Examples of uncommon infections that cause lymphoma also include Tuberculosis, some sexually transmitted infections such as syphilis, toxoplasmosis, Which passes through infected cat litter.
- cancer: Cancer is one of the conditions that can cause the swelling and enlargement of the lymph nodes, where cancer can originate from the lymphatic system itself, which is called lymphoma or lymphoma. Hematopoietic tissues, including the bone marrow and the lymphatic system, are called Leukemia. Cancer may spread from other parts of the body to the lymph nodes. This is called metastasis or the migration of cancer cells.
- Immune system disorders: Immune System Disorders are one of the reasons that can lead to lymphoma, such as Rheumatoid Arthritis, which affects the lining of the joints, and lupus, Targets various parts of the body such as joints, skin, kidneys, blood cells, heart, and lungs.
