ANATOMY

Detailed explanation-1: -In most insect species, the trachea is the primary organ responsible for respiratory function. Spiracles are exterior openings found on insects. The air enters the body through these spiracles and travels to the trachea, which is part of the internal respiratory system.

Detailed explanation-2: -For insects, respiration is separate from the circulatory system. Oxygen and carbon dioxide gases are exchanged through a network of tubes called tracheae. Instead of nostrils, insects breathe through openings in the thorax and abdomen called spiracles.

Detailed explanation-3: -Most insects respire through a system of tubes called tracheae that connect to the air via spiracles that can be actively opened or closed (1). Tracheal tubes form a complex network of gas-filled vessels that divide throughout the body segments, legs, and wings.

Detailed explanation-4: -Insects have a tracheal respiratory system in which oxygen and carbon dioxide travel primarily through air-filled tubes called tracheae. Usually the tracheal system penetrates the cuticle via closeable valves called spiracles and ends near or within the tissues in tiny tubes called tracheoles.

Detailed explanation-5: -In the tracheal system, the respiration process in an organism is carried by air tubes or trachea. The tracheal openings spiracles are present on the side of the body of the organism. It is through the spiracles that the oxygen and carbon dioxide gas is circulated throughout the body.
