Accepted Answer

The opening to the tracheal system in insects is called spiracle. It is located on the lateral sides of the insect's body and connects to a network of tubes called tracheae, which delivers oxygen directly to the body tissues. The other options, such as alveolus, bronchus, and stomata, are not relevant to the respiratory system of insects.
