👉 Meridians are points along the body's lymphatic system, which help to transport and process fluid from the blood. They are also known as lymph nodes or lymph glands, and they play a significant role in the immune system of the body. The term "meridians" comes from Greek roots meaning "to bring together," "to unite," or "to connect." In Chinese medicine, meridians are thought to be associated with various organs, tissues, and systems within the body.
