Hi
How do insects breathe?
The mechanism of breathing in insects -
Insects have small openings on the sides of its body. These openings are called spiracles. Insects have a network of air tubes called tracheae for gas exchange. Oxygen-rich air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches every cell of the body. Similarly, carbon dioxide from the cells goes into the tracheal tubes and moves out through spiracles. These air tubes or tracheae are found only in insects and not in any other group of animals.
