Question

Quizplus · Accepted Answer

The tracheoles in insects are small, thin-walled tubes that deliver oxygen directly to the body tissues. Similarly, the skin of an earthworm is also thin and moist, and is responsible for gas exchange with the environment through a process called cutaneous respiration. Therefore, the skin of an earthworm is analogous in function to the tracheoles in insects. The bronchi in a human, trachea of a bird, and skin of a reptile are not analogous in function to the tracheoles in insects.
