They are called spiracles, tiny tubes alongside the insect's body which allow it to receive air. Kind of like gills, but for insects.
Good luck!
tracheal system
The respiratory system of insects is called the tracheal system. It consists of a network of branching tubes called tracheae that deliver oxygen directly to the cells and remove waste gases. These tubes have openings called spiracles on the surface of the insect's body.
The insect respiratory system operates by passive exchange of gasses through tiny holes called spiracles in their abdomen.
The respiratory surface for a grasshopper is also known as spiracles, any of several paired apertures in the cuticle of an insect, by which air enters and leaves the trachea. I got this information from the Campbell biology book, wiki, and the dictionary.
The very first part of the respiratory tract are the openings into the nasal cavities called the nares.
Air can be taken into the respiratory system at the mouth and the nose.
Yes.The bronchi are the openings to the lungs
The two nose holes are called nostrils. They are openings leading to the nasal cavity, which is part of the respiratory system.

tracheal system
Insects have openings called spiracles along their abdomens that allow them to take in oxygen. These spiracles lead to a network of tubes called tracheae, which deliver oxygen directly to the insect's cells. This respiratory system is adapted for the efficient exchange of gases in insects.
An insect's respiratory surface is kept moist primarily through the presence of a thin layer of fluid that lines the tracheae and tracheoles, which are the tiny tubes that deliver oxygen directly to tissues. Additionally, the spiracles, or openings on the insect's body, can regulate airflow and moisture exchange, helping to maintain humidity within the tracheal system. This moisture is crucial for gas exchange, as it allows oxygen to dissolve and diffuse into the insect's cells.
