Lymph nodes are small, bean-shaped structures found throughout the body. They are part of the lymphatic system, which is responsible for filtering and draining lymph fluid from tissues and organs. Lymph nodes are connected by a network of lymphatic vessels.
Lymph nodes are typically found in clusters in specific regions of the body, such as the neck, armpits, groin, and abdomen. They vary in size, ranging from a few millimeters to about 1-2 centimeters in diameter. However, some lymph nodes, such as those in the neck, can become enlarged during an infection or illness.
The main function of lymph nodes is to filter lymph fluid, which contains waste products, toxins, and foreign substances, such as bacteria or viruses. As lymph fluid flows through the lymph nodes, specialized immune cells called lymphocytes and macrophages help identify and destroy any harmful substances present. This process helps to prevent the spread of infection or disease throughout the body.
Lymph nodes also play a crucial role in the immune response. When an infection or illness occurs, lymph nodes can become swollen and tender as they work to produce more immune cells to fight off the invading pathogens. This is why swollen lymph nodes are often a sign of an underlying infection or inflammation in the body.
In summary, lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They filter lymph fluid, help fight off infections, and play a vital role in the body's immune response.
