[Answer] What do insects do with their spiracles?

Step 1 : Introduction to the question "What do insects do with their spiracles?"

...The insect uses its spiracle to move air into their tracheal system. Since they lack lungs, insects use their spiracles to take in oxygen and release carbon dioxide into the surrounding air. Muscle contractions serve to open and close the spiracles. Once pulled into the body, oxygen molecules move throughout the insect's body through its tracheal system. The end of each tracheal tube is covered by a tracheole. This is where oxygen is absorbed into the fluid that fills up the tracheole. From there, the oxygen is diffused into the cells. Source:
