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 liquids, and also comprise the chewing mandibles that are involved in processing solid food. The mouth is closed when the sucking pump activates, thus food is pumped into the oesophagus, a tube extending through the head and thorax. Two sets of salivary glands one in the head, and the other in the thorax. Both share a common duct that conveys saliva into the buccal cavity where it mixes with the food to dilute, soften, or lubricate it as it is ingested. 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.
