WebCoordination of air flow with blood flow: A. Gas exchange in the alveoli is most efficient when air flow equals the rate of blood flow. B. Local controls within the lungs correct imbalances in air and blood flow by constricting or dilating both bronchioles and arterioles. 9. Explain the control of respiration in vertebrates: I. WebThe tracheae connect to the outside environment through openings in the insect body wall called spiracles. Spiracles are generally found laterally along an insect's thorax and abdomen. They can have filters or valves that open only when gas exchange is taking place. WebThe tracheal system consists of a number of tubes that open to the exterior by paired respiratory pores (spiracles) and is similar to that of insects. Diffusion of gases occurs within small fluid-filled tubes that ramify over the internal organs.
