Does insects have heart and lungs?
Help please. I can't find any information that states whether insects do generally have hearts and lungs, or not.

Bugs do not have lungs, as read here, but they have another type of breathing mechanism: http://www.redorbit.com/news/science/1517/do_bugs_...
Bugs dont have hearts either. Arguably, this site says they do, but leave that to the scientists. http://www.geocities.com/scribblyfaq/insectheart.h...

Their body system is a lot simpler than ours. Instead of a true brain, they have a collection of nerves called the Cerebral Ganglion. They will also have thoracic ganglia down the spinal column. They don't have lungs, as they have what is called an open circulatory system. This means that they have tiny holes in their exoskeleton called spiracles that allows air to pass though the body. This is why insects are so small, this kind of respiratory system is very inefficient and won't carry enough oxygen to organs in a larger animal.
