-equipped with sensory hairs
-sensory functions, food handling, swift and efficient walking legs, and swimming appendages
Air is piped directly to the ______.
cells
Most terrestrial arthropods have a highly efficient _________, which delivers O2 directly to the tissues and cells and makes a high metabolic rate possible.
