Answer 2

• Insects such as grasshoppers, cockroaches, and houseflies lack lungs as part of their respiratory system.
• For breathing, they use a basic gas exchange mechanism.
• They have a tracheal system that allows oxygen to be delivered directly to each cell in the body.
• They breathe using lengthy tubes known as tracheae.

• The tracheal system is the cockroach and grasshopper's breathing system, which is made up of a network of trachea.

• They breathe using spiracles, which are little apertures in their skin.

• The muscular spinchters govern these apertures.

• The spiracles, which open into the tracheal tubes, allow them to take in oxygen-rich air.
