Answer
The hemolymph is like the water pumping out of an outdoor fountain in several ways. First, the hemolymph is a fluid that bathes the body cells, just like water bathes the fountain and what's in it. Second, the hemolymph is pumped by the contractions of the heart into interconnected sinuses, or spaces between the organs. The water in the fountain, is pumped out from a single place just like the hemolymph is. Third, when the heart relaxes, the hemolymph is drawn back through pores, just like the water when it returns back in the fountain through special opening that collect the water to be pumped again.
