They rely on diffusion to supply oxygen and nutrients to all parts of the body.

it supplies the heart with glucose and oxygen
4 of 7
what happens in an open circulatory system of an insect?
the insects blood fills up the blood cavity instead of being contained in blood vessels, the blood circulates slowly and therefore it cannot be used to deliver oxygen to the tissues instead there are special tubes which deliver air to respiring cells
