Insects breathe with a network of tiny tubes called tracheae.

Tracheae are air tubes that transport air directly to the insect's cells, allowing gas exchange between the air and the cells. 

The tracheae open at the spiracles, which are small openings on the body of the insect. 

Air enters the spiracles and travels to the insect's cells via the tracheae. 

Tracheal respiration is the name given to this type of breathing.
