Question
Describe the path taken by carbon (IV) oxide from the tissues of the insect the atmosphere.
Answer
During respiration, cells in insect tissues produce carbon dioxide as a waste product. This CO2 diffuses out of the cells and enters the insect's tracheal system, a network of tubes that transports gases. The tracheal tubes carry the CO2 toward the spiracles, openings on the insect's body. From there, the CO2 exits the insect's body and is released into the atmosphere.
