21. Acerentomids are not tracheated, and instead use cuticular gas exchange . 22. Different structures are involved in gas exchange in other vertebrates. 23. Ventilation volumes and respiratory gas exchanges were also monitored, before, during and after exercise. 24. Later divisions including the respiratory bronchiole, alveolar ducts and alveoli, are specialized for gas exchange . 25. They supplement this with gas exchange through the skin. 26. Gas exchange patterns in insects can range from continuous, diffusive ventilation, to discontinuous gas exchange . 27. Blood travels through the arterioles and moves into the capillaries where gas exchange can occur. 28. The neopulmonic parabronchi never make up more than 25 % of the gas exchange surface. 29. Gas exchange patterns in insects can range from continuous, diffusive ventilation, to discontinuous gas exchange.30. Gas exchange patterns in insects can range from continuous and diffusive ventilation, to discontinuous gas exchange.
