The large airways that branch off the trachea are the mainstem bronchi. These branch into progressively smaller bronchioles.

The correct order of structures in the respiratory system begins with the nasal cavity or mouth, where air enters. It then travels down the pharynx and larynx before passing through the trachea. From the trachea, air moves into the bronchi, which branch into smaller bronchioles, leading to the alveoli where gas exchange occurs.

The spiracles and trachea are structures that enable respiration in insects. Air enters the body through the spiracles and then travels through the trachea. Spiracles are tiny holes in an insect's exoskeleton, and the trachea is a network of tubes.
