Q1) What are Lymph nodes?
Lymph nodes, also known as lymph glands, are small, bean-shaped structures located throughout the body as part of the lymphatic system. The lymphatic system is a complex network of vessels, nodes, and organs that plays a crucial role in maintaining fluid balance, filtering out harmful substances, and supporting the immune system’s functions.
