Lymfatiehissä

Lymfatiehissä is a term of Swedish origin that translates to "lymph nodes" in English. Lymph nodes are small, bean-shaped organs found throughout the body, playing a crucial role in the immune system. They are part of the lymphatic system, a network of vessels and organs that transport lymph, a clear fluid containing white blood cells.

These nodes are strategically located along the lymphatic vessels and act as filters for the lymph. As lymph flows through the nodes, specialized white blood cells called lymphocytes and macrophages identify and destroy foreign substances such as bacteria, viruses, and abnormal cells. This filtering process is vital for preventing the spread of infection and disease.

Lymph nodes can become enlarged when the body is fighting off an infection or illness. This swelling is a common sign that the immune system is actively engaged. The location of swollen lymph nodes can sometimes help pinpoint the source of an infection. For instance, swollen nodes in the neck might indicate a throat infection, while those in the armpit could relate to an infection in the arm or breast.

Diseases affecting the lymph nodes themselves can include lymphoma, a type of cancer that originates in lymphocytes, and lymphadenopathy, which is the general term for enlarged lymph nodes. Understanding the function of lymph nodes is important for comprehending the body's defense mechanisms and the impact of various health conditions.
