Answer :-

=) In cockroach , respiration happens through a little openings on the sides of its body called spiracles. At the point when the air enters the respiratory arrangement of a cockroach through these outer openings, spiracles go about as solid valves, prompting the inside respiratory framework. The respiratory organ of cockroach is known as tracheae .

The tracheae works to balance the weight inside the framework. As the oxygenated air from the climate goes into the cockroach's body through the spiracles into the tracheal cylinders, it enters into the diverse cells and tissues of the body, where the oxygen gas is used to discharge vitality .
