Which of the following is a function of the lymphatic system?

The lymphatic system plays a crucial role in maintaining fluid balance within the body by recovering excess tissue fluid. As blood circulates through the body, some fluid leaks from the blood vessels into the surrounding tissues. If this fluid were not returned to the circulation, it could lead to swelling and tissue damage. The lymphatic vessels collect this excess fluid, known as lymph, and transport it back into the bloodstream. This function is essential for preventing edema and ensuring that tissues remain healthy and properly hydrated.

While nutrient absorption is primarily associated with the digestive system—specifically the absorption of fats through the small intestine—the production of hormones is mainly the function of the endocrine system, and the regulation of body temperature primarily involves the integumentary system and the circulatory system. Thus, the recovery of excess tissue fluid is a distinct and vital function of the lymphatic system.
