Network of tubes called Tracheae are the respiratory organs of

The correct answer is Insects.

Key Points

• All living organisms respire to get energy from food.
• The process of breakdown of food in the cell with the release of energy is called cellular respiration.
• A network of tubes called tracheae are the respiratory organs of insects.
• Tracheal tubes help insects to transport atmospheric air within the body.
• Oxygenated air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches the body cell.
• Carbon dioxide from the cells moves to the tracheal tubes and moves out through spiracles.

Additional Information

• Reptiles, birds, and mammals respire through the lungs.
• Amphibians like frogs can respire through their moist skin.
• Earthworms breathe through their moist skins(cuticle).
• Fishes use gills for gas exchange.
• Mussels breathe through their gills.
