Question

Describe the gaseous and circulatory systems of an insect

Answer 1

Gaseous exchange in insects occurs through a system of air-filled internal tubes, the tracheal system, the finer branches of which extend to all parts of the body and may become functionally intracellular in muscle fibers. Thus oxygen is carried in the gas phase directly to its sites of utilization.

The insect's circulatory system has a single tubular muscular vessel, the dorsal vessel, which is supported by the muscular dorsal diaphragm. Hemolymph moves into the dorsal vessel through one-way valves located along the length of the organ known as ostia. ... The insect nervous system helps to mediate such coordination
