Answers

Answered by kashvichaurasia819

Explanation:

Insects have a network of tubes called tracheae or tracheal tubes, which are responsible for their respiration. Oxygen enters these tubes through several spiracles, which are valve-like openings in the exoskeleton. ... Small muscles in each spiracle control their opening and air flow.
