Do woodlice have hearts

Yes, woodlice do have a heart, but it is quite different from the hearts of vertebrates. Woodlice possess a simple heart that pumps hemolymph (a fluid equivalent to blood) through their open circulatory system. This heart is located in the thorax and helps circulate nutrients and oxygen throughout their bodies. However, their circulatory system is less complex than that of animals with closed circulatory systems.
