Why, even thoough they have an open circulatory system, can flying insects like flies beat their wings with great speed?

Description : Why, even thoough they have an open circulatory system, can flying insects like flies beat their wings with great speed?

Last Answer : In insects the circulatory system is open but this system does not participate in the gas exchange process and in oxygen supply to the tissues. Gases go in and out through the independent ... can supply the great oxygen demand of its fast-beating wing muscles even having open circulatory system.

The closed circulatory system is more efficient. Since blood circulates only inside blood vessels it can do it with more pressure reaching farther distances between the organs where hematosis happens and the peripheral tissues. In addition the circulatory speed also heightens making possible more oxygen supply to great consuming tissues, like the muscle tissues that then can perform faster movements. Animals with an open circulatory system (with the exception of insects that do gas exchange independently from the circulation) are generally slower and have a low metabolic rate.
