Which components primarily make up the lymphatic system?

The lymphatic system is primarily composed of lymph, lymph nodes, and lymph vessels. Lymph is a clear fluid that circulates through the lymphatic vessels, collecting waste products, bacteria, and foreign particles, and transporting them through the system. Lymph nodes act as filtration points, where lymph is cleansed of pathogens and other harmful substances, and they also play a crucial role in the immune response by producing lymphocytes. Lymph vessels are the network of channels that carry lymph throughout the body, allowing for the distribution of immune cells and the retrieval of excess interstitial fluid. This configuration makes the lymphatic system integral to both immune function and fluid balance in the body.
