What is the primary function of the lymphatic system?

The primary function of the lymphatic system is to transport lymph, remove waste, and play a key role in immune function. Lymph is a fluid that circulates through the lymphatic vessels, carrying nutrients, waste products, and immune cells throughout the body. As part of the immune system, the lymphatic system helps to identify and eliminate pathogens, such as bacteria and viruses, facilitating a response from the immune cells that reside within lymph nodes.

Additionally, it plays a crucial role in maintaining fluid balance by collecting excess interstitial fluid and returning it to the bloodstream. The removal of waste products is vital for tissue health and aids in preventing infections, further underscoring its importance in overall health and immune response. This multifaceted role makes the lymphatic system essential not only for fluid balance but also for protecting the body against disease and infection.
