The primary method of breathing in arthropods involves a tracheal system, which is an intricate network of tiny tubes that deliver oxygen directly to their tissues. While spiracles, which are openings on the outside of the body, serve as entry points for air into this tracheal system, they are not the method of breathing themselves. The spiracles allow for the exchange of gases but do not perform the actual respiration.

Understanding the structure and function of the tracheal system is crucial in recognizing how arthropods are able to efficiently transport oxygen throughout their bodies. This method is particularly important for terrestrial arthropods, enabling them to thrive in a variety of environments.

In contrast, lungs and gills serve as respiratory structures for other types of organisms. Lungs are utilized by some terrestrial animals for gas exchange, while gills are specialized for extracting oxygen from water, which is not applicable to most arthropods.
