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. WebApr 2, 2024 · Unlike humans, insects do not have lungs. Instead, they have a system of tubes called tracheae that distribute air throughout their body. These tubes open to the outside through pores called spiracles, which are located on the insect's exoskeleton.

Oxygen diffuses from the tracheae into the tracheoles and then into the cells, while carbon dioxide diffuses out of the cells and into the tracheal system to be expelled through the spiracles. The Role of Muscles in Insect Respiration

WebBecause the exoskeleton is impermeable respiratory gases must move into the insect through a series of internal tubes called tracheae or tracheal tubes. These tracheae are highly branched helping to increase the Surface area : volume ratio available for gas exchange. Tracheoles 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.
