Even having low pressure and low speed circulatory system, because it is a lacunar (or open) circulatory system, insects carry out extremely exhaustive and fast movements with their muscle fibers, like wing beating. This is probable because in these animals respiration is independent from open circulation. Gas exchange is completed with high speed and effectiveness by tracheal system which puts cells in direct contact with air. Muscles can then work hard and fast.
