Document Summary
The alimentary tract and digestive system extends from the mouth to the anus as a tube running the complete length of the bee. Mouthparts make a complex and sealable tube for sucking up. The mouth is closed when the sucking pump activates, thus liquids, and also comprise the chewing mandibles that are involved in processing solid food food is pumped into the oesophagus, a tube extending through the head and thorax. Proventriculus acts as a valve, regulating the flow of material from the oesophagus (including the honey stomach) into the ventriculus, the main digestive organ and the rever. Anterior intestine a tube at the end of the ventriculus in which food waste is pumped into. Overwintering bees store large amount of feces in the rectum. Mass defication is part of thermoregulation in the giant honeybee. Excretion is mostly carried out by the malpighian tubules .
