The mouthparts of the bee include the proboscis, which allows the bee both to draw up nectar from flowers, and later to regurgitate it to other workers in the hive. There, it's processed into honey.

This picture focuses on the bee's tongue, called the glossa. This organ is not only involved in feeding, but also plays a role in communication. The glossa is used to lick up the queen's pheromones, the chemical signals the queen produces to give orders to her workers and drones.
