lümfisõlmede

Lümfisõlmed, known in English as lymph nodes, are small, bean-shaped organs scattered throughout the body's lymphatic system. They are a crucial part of the immune system, acting as filters for lymph fluid. Lymph fluid, which circulates throughout the body carrying waste products and immune cells, passes through the lymph nodes. Within these nodes, specialized white blood cells, particularly lymphocytes and macrophages, are present. These cells are responsible for detecting and destroying foreign substances such as bacteria, viruses, and abnormal cells like cancer cells.

When the body is fighting an infection, lymph nodes can become swollen and tender. This swelling, often referred to as swollen glands, is a sign that the immune system is actively working. The size and tenderness of lymph nodes can vary depending on the severity and type of infection or inflammation. Palpable lymph nodes are often found in areas such as the neck, armpits, and groin.

The lymphatic system, which includes lymph nodes, also plays a role in maintaining fluid balance in the body by returning excess fluid from tissues to the bloodstream. Lümfisõlmed are strategically located along the lymphatic vessels, enabling them to effectively monitor and respond to threats throughout the entire body. Their primary function is to initiate an immune response when pathogens or abnormal cells are detected.
