Question

Quizplus · Accepted Answer

The backflow of lymph in the larger lymph vessels is prevented by valves, which are similar to the ones found in veins. These valves ensure that lymph flows in the right direction and does not flow backward. The lymph pump aids in the flow of lymph, but it does not prevent backflow. Dilation and the heart are not involved in preventing backflow of lymph.
