Hearts: Sort of. Insects have an open circulatory system, meaning their organs just float in blood. It's similar to how human organs float in lymph, so we call insect blood"hemolymph.". However, insects do usually have a tube on their back that has holes to take in blood and pumps it up to the front of the insect. read more

Insects do have hearts - sometimes several of them! The heart in insects is a contactile blood vessel that extends the length of the animal. Contractions start at the posterior end & progress anteriorly. As noted by several of the other posters, the insect circulatory system is an open system. read more

Insects don't have veins or arteries, but they do have circulatory systems. When blood is moved without the aid of vessels, the organism has an open circulatory system. Insect blood, properly called hemolymph, flows freely through the body cavity and makes direct contact with organs and tissues. read more
