lymfkörtlarnas

Lymfkörtlarna, also known as lymph nodes, are small, bean-shaped organs that are part of the lymphatic system. They are found throughout the body and play a crucial role in the immune system. Lymfkörtlarna act as filters, trapping foreign substances such as bacteria, viruses, and cancer cells. Within the lymph nodes, specialized white blood cells, called lymphocytes, identify and destroy these harmful invaders. When the body is fighting an infection, the lymph nodes may become swollen and tender, which is often referred to as swollen glands. This swelling indicates that the immune system is actively working. There are hundreds of lymph nodes in the body, clustered in areas like the neck, armpits, and groin. They are connected by a network of lymphatic vessels that carry lymph fluid. This fluid circulates throughout the body, collecting waste products and transporting immune cells. The lymphatic system, including the lymph nodes, is essential for maintaining health and defending against disease.
