Quizplus · Accepted Answer

The lymphatic system is responsible for returning tissue fluid, also known as lymph, to the circulatory system. This helps to maintain fluid balance in the body. Additionally, the lymphatic system plays a key role in fighting infections by filtering out and destroying pathogens in the lymph nodes. Therefore, the best choice is B, which accurately describes the two main functions of the lymphatic system. Choices A, C, and D are incorrect because they either include functions that are not performed by the lymphatic system (coagulating blood, producing hormones that regulate the immune system) or do not include both of the correct functions (fighting infections, returning tissue fluid to the circulatory system).
