The proboscis of a honey bee is composed of a long, tube which acts as the tongue. The tubular, hairy structure of the proboscis is coupled with the ability to extend and retract. The end of the proboscis is outfitted as a spoon-shaped structure. This structure coupled with the ability to extend and retract at will provides the function of ingesting liquids such as water and honey.
The anatomy of the human eye performs the function of capturing light and converting it into electronic signals sent to the brain. The outermost dome-shaped transparent layer of the eye, labeled the cornea, has the ability to capture light and focus it through the pupil encased by the iris and further focused by the lens. The controlled light sent through the lens…show more content… The structure of the varieties of beaks plays a large role in their function. The beaks of raptors, or meat-eaters, are generally shaped with the upper half of the beak provided with an extrusion, resulting in the upper half being larger than the lower half of the bird’s mouth. The extruding half shapes itself into a hook. This subsequent hook allows the raptor to seize its prey and fracture the skull or bones. The structure of this beak also allows the bird of prey to pierce and pull apart the meat and flesh of its victim. Another particular beak present in bird species are the ones attributed to nectar-based diets. Aviators with a nectar diet are characterized by long, thin, tube-shaped beaks which house extensive tongues. The tongue and beak give the bird the ability to reach and suck the nectar of flowers. Another form of beaks present in aviators are the ones attributed to scooping. Birds with beaks necessary for retrieving food in this manner generally have the beak structure with a pouch. The large pouch is subsequently positioned in the lower half of their bill allowing the species the ability of containing a large amount of space. This pouch allows the bird to envelop their diet in a singular use of their bill and ingest moderately large prey such as…show more content… An example would be the circulatory system. The circulatory system is characterized as the system which allows the transport of oxygenated and deoxygenated blood throughout the body of an animal. It is distinguished as a “closed-loop system”. The cardiovascular system is composed of capillaries, arteries, veins, and the heart. The capillaries, arteries, and veins can be characterized as blood vessels. Blood vessels can be defined as thin, tubular structures allowing the transport of blood cells within them. Blood vessels generally share the same function of a pipe. The tube-shaped structure of blood vessels permits the flow of blood cells throughout the body in two distinct circuits in a closed loop. It is the subsequent structure of the closed-loop system throughout the organism which allows the travel of oxygenated blood pumped out of the heart and deoxygenated cells back
