ANATOMY

Detailed explanation-1: -Tracheae connect with the atmosphere through openings called spiracles, which usually have closable valves. Some insects, including grasshoppers, have air sacs that are enlarged tracheae lacking the normal exocuticle and taenidia and are hypothesized to act as bellows to aid convective airflow (for review see Refs.

Detailed explanation-2: -The grasshopper abdomen has longitudinal tracheae that run along the midgut, heart, nerve cord, and lateral body wall. Transverse tracheae run from each spiracle to the longitudinal tracheae. Dorsal air sacs attach near each spiracle.

Detailed explanation-3: -Tracheal System of an Insect Very active, flying insects need a more rapid supply/intake of oxygen. They create a mass flow of air into the tracheal system by: Closing the spiracles. Using muscles to create a pumping movement for ventilation.

Detailed explanation-4: -Instead of breathing in air, grasshoppers use tiny holes located on their abdomen called Spiracles; the Spiracles are located along both sides of the abdomen and are used to bring air into the grasshoppers body.

Detailed explanation-5: -Insects have a tracheal system for gas exchange. Air enters the insect through pores in their outer surface called spiracles. Air then moves down the trachea, which branches off into a large number of tracheoles. The walls of the tracheoles are thin and porous, speeding up diffusion of gases to cells.
