The heart of an insect is very different from that of a human or any other mammal. It is a tube running from the rear of the insect to inside the head. More or less matching the bodily segments the basic tube shape is formed into segments with one chamber in each, but the more advanced the insect type, the more the heart is modified to fit the body and the fewer segments remain. For instance there are about six segments in the insect's head, but modern insects have no heart chambers in the head at all. In the hearts of the most derived (or advanced, if you prefer the word) insects, such as ants, bees and wasps, also some flies, there are five chambers. with five pairs of holes to match and four one-way valves between the chambers.
