What is the relationship between the lymphatic and circulatory systems?

The lymphatic system is responsible for filtering and returning excess interstitial fluid to the bloodstream, which involves processing and filtering lymph. This fluid contains various substances, including proteins, waste products, and immune cells. In contrast, the circulatory system serves to transport blood throughout the body, delivering essential substances like oxygen and nutrients to tissues and organs while removing metabolic waste products.

The relationship between these two systems is crucial because while the lymphatic system helps maintain fluid balance and protects against pathogens through its filtration capacity, the circulatory system is driving the transport of blood, which is essential for delivering cells and substances necessary for bodily functions. Therefore, the statement that the lymphatic system filters plasma and the circulatory system transports blood accurately encapsulates the cooperative nature of these systems in maintaining overall homeostasis in the body.
