Insects do have a respiratory system. The using organs called spiracles to introduce oxygen from the atmosphere into their bodies. These spiracles then let oxygen flow into the tracheal system which is a system of tubes that delivers oxygen to the parts of the body where it is needed.
Some vertebrates eg. sharks and stingrays and some arthropods eg. the indian moon moth and the cricket.
The digestive system of insects includes a foregut (stomodaeum - the mouth region), a hindgut (proctodaeum - the anal region), and a midgut (mesenteron). The grasshopper's nervous system is controlled by ganglia, loose groups of nerve cells which are found in most species more advanced than cnidarians. The grasshopper's reproductive system consists of the gonads, the ducts which carry sexual products to the exterior, and accessory glands. Grasshoppers have open circulatory systems, with most of the body fluid filling body cavities and appendages.

After being ground up in the gizzard, food passes to the grasshopper's stomach. While in the stomach nutrients from the food are absorbed into the haemocoel of the grasshopper's circulatory system.

Tracheole (trā'kē-ōl') is one of the fine branching tubes of the trachea of an insect, which penetrates the tissues to provide oxygen ..... The trachea is a part of the respiratory system
A grasshopper's tracheal system can be compared to that of a humans. Their air sacs store carbon dioxide and oxygen when respiration is taking place.

Tracheal is not a scientific term used for classification. It is a part of the respiratory system in insects, functioning to deliver oxygen to tissues.
