1.1 Nodes and function of lymph nodes In the human body, in addition to the dynamic and venous circulatory system, there is also a lymphatic circulation system consisting of lymphatic vessels (lymphatic vessels) and lymph nodes (nodes).
Lymph nodes are usually oval in shape, ranging in size from a few millimeters to about 1-2cm. In terms of function, the lymph nodes are part of the hematopoietic system (the hematopoietic system includes bone marrow, thymus, liver, spleen and lymph nodes) with two main functions:
Directly imprisoning and destroying bacteria, viruses, foreign cells (such as cancer cells) when they enter the body; Indirectly destroy bacteria, viruses, foreign cells and create immunity for the body through the production of antibodies. The lymph nodes are distributed almost throughout the body, from the visceral organs, the abdomen to the subcutaneous soft tissues. When the superficial lymph nodes under the skin enlarge, they can be palpated. Usually, the most palpable nodes are the cervical, inguinal, and axillary nodes.
1.2 What is lymphadenopathy? Normally, lymph nodes are submerged, not palpable. It is only when the lymph nodes have to work hard to fight disease that they swell. Because the function of the lymph nodes is to produce lymphocytes and antibodies against pathogens. Swollen lymph nodes (also called swollen lymph nodes) are small pea-sized masses on the body. These tumors grow along the joints of the wrists, hands, ankles or feet, armpits, neck, groin, etc. They are oval or round in shape, often with fluid inside. When pressing on the swollen lymph nodes, the patient will feel pain.
