Antenna - are the main sensory organs, providing information on touch, smell, taste and hearing. There are 170 odour recptors on an antenna, giving bees an extremely well-developed sense of smell.
Brain - bees have excellent learning abilities. Their brains processes information used in navigation and communication as well as memory.
Compound eye - A compound eye is made up of many eye units. Each unit takes in a separate image and transfer the information to the brain where it is pieced together into a single image. This protects the eyes from the harshness of daylight and to process information more quickly.
Glossa - is a long cylindrical "tongue" which can be extended and dipped into nectar.
Heart - unlike mammals, honey bees and insects have an open circulatory system, meaning their blood is not contained within tubes like veins or arteries. The blood is free-flowing throughout the body cavity and is pumped via the heart. The heart is the structure in red, and acts like a pumping leaky tube to help move the blood through the body.
Honey stomach - A storage sac used to carry nectar. It is hardened to prevent its contents from entering the body.
Hypopharyngeal gland - used in the production of royal jelly, used to make queen bees.
Mandibles - are mouthparts used to manipulate solid substances.
Ocelli - are the simple eyes as opposed to compound eyes. Bees have 2 large compound eyes and 3 ocelli. Compound eyes have poor image resolution, but possess a very large view angle and the ability to detect fast movement. Ocelli provide information for the bee on light intensity; bees can see ultra-violet light, so they can navigate using the sun even on very cloudy days.
Spiracle - the breathing system in insects is a series of hollow tubes connected to air sacs in the body. The openings of these hollow tubes are called spiracles.
Stinger - puncture the skin and pumps venom into the wound. In worker bees the stinger has a barbed end. Once pushed into the skin of a mammal the stinger cannot be withdrawn from muscle tissue and the stinger is ripped out of the bee. The venom sac will remain with the stinger. Queen bees have a longer and un-barbed stinger. Drones (males) do not have a stinger.
Stomach - unlike the honey stomach, the regular stomach is used to help digest food for the bee. The processed food passes through the intestines and then out.
Venom sac - holds venom. The sac contracts repeatedly to pump venom through the stinger.
Wing muscles - bees beat their wings 230 times a second! The wings have 8 sets of muscles that move these wings in the precise way necessary for flight. The wings coupled together by a row of hooks on the hind wing that grip in a groove that exists on the rear edge of the fore wing.The driving force results from a propeller-like twist given to each wing during the upstroke and the down-stroke. Slight variations in the actual angles of the wings determine whether the bee hovers, moves forwards or turns. When bees need to lift heavy cargo (nectar and pollen), they don’t flap their wings faster – they stretch out their wing stroke.
