Respiratory system of insects-arthropod class
Explain how respiratory system of insects (with its independence among respiration and circulation) associated to the motor agility of various species of this arthropod class?
Expert
Even containing low speed and low pressure circulatory system, as it is a lacunar (or open) circulatory system, insects execute extremely fast and exhaustive movements with their muscle fibers, such as wing beating. This is probable since in such animals the respiration is independent from open circulation.
Gas exchange is completed with great speed and effectiveness by the tracheal system which puts cells in direct contact with the air. Muscles can then work hard and fast.
