Answer
Arteries take blood (fluid) away from the heart. Lymph is fluid that comes from interstitial spaces between cells. This fluid enters the lymphatics by diffusion and through spaces between lymph capillary endothelial cells. Lymph capillaries have closed ends and lymphatics have one way valves . Consequently lymph flows toward one destination-- towards the heart. The lymphatic system is not a circulatory system
Work Step by Step
The lymphatic system is not a circulatory system. It takes lymph to one destination-- towards veins and eventually the heart,. There is no need for arteries to take fluid back to the lymphatic system. The fluid in the lymphatic system is interstitial fluid picked up by lymph capillaries from interstitial spaces
