Q. How is the respiratory system of insects with its independence between respiration and circulation related to the motor agility of some species of this arthropod class?
Even having low pressure and low speed circulatory system, since it is a lacunar (open) circulatory system, exhaustive movements with their muscle fibers, and insects perform extremely fast like wing beating. This is feasible because in these animals the respiration is independent from the open circulation. Gas exchange is done with great efficiency and speed by the tracheal system that puts cells in direct contact with air, Muscles can then work hard and fast.
