Question
The respiratory system in ______ is called the tracheal system.
Correct Answer
Option A is the correct answer.
Detailed Explanation
The tracheal system is a distinctive respiratory system found in insects and some other arthropods. It consists of a network of air-filled tubes (tracheae) that branch throughout the body, directly delivering oxygen to tissues and removing carbon dioxide. Vertebrates, fishes, and birds have lungs or gills for respiration.
Hint
Think about the unique breathing structures found in arthropods, particularly those that fly.
