    Yes.

    Their hearts are sort of like one of our arteries, but open at both ends. An insect itself is approximately a hollow, tube shaped shell. Its organs actually float freely around in a pool of its blood, but this substance is more like our sweat than our own blood. The blood carries food and other materials around inside the insect's shell. Like in an aquarium, this process is most efficient if the fluid is circulating, and the insect heart draws blood in from one end of the insect's body and delivers it to the other end. The blood then drifts back to the other end to get pumped again. Insects get their oxygen directly from the air by a dence network of air tubes running through their bodies. The tubes open through tiny holes in the insect's shell. An insect's heart does not carry oxygenated blood like our own does, rather it just keeps the body fluid circulating.

    Yes, but it powers a different type of circulatory system. Mammals (including humans) have a closed circulatory system, where our heart and lungs work together with our hearts beating regularly and involuntarily. Insects have an open circulatory system, where their hearts beat only when oxygen supplies run low in what passes for their blood (hemolymph). The insect breathes through holes in its abdominal segments (down the sides of its belly). An insect only breathes in and its heart beats only when it needs oxygen, which is why you'll see an insect's abdomen go in and out rapidly after you've exhausted it by chasing it around the yard.

    Source(s): I studied a lot of entomology while earning my biology degree.

    Sort of. "Because insects do not have veins and arteries like us and the rest of the vertebrates, (they do not need to), they do not have a complicated heart like ours either. The insect heart it is basically a tube, sealed at one end, which runs along their back. It beats regularly thus swishing the blood in and out and around the body."

    in insects open vascular system is present. in this system there are 5-7 sinuses are present which are simillar in the function of heart so we can say they have 5-7 hearts

    yes they do-some even have more than one like nematodes/roundworm (earthworm) it has many along it's long thin body. the compotents of the blood maybe chemically different but the principle is the same.

    yes, if you are talking about the organ. if you are referring to them having feelings of love and compassion, then there is no way for any human to know.
