Like other insects, cockroaches have tracheae, which are tubes that are attached to spiracles (holes on the surface). The tubes open and close to allow carbon dioxide to diffuse out and oxygen to diffuse in. The oxygen goes directly to the cells through a network of more tubes.
no lungs they have

None. Insects don't have lungs, they have breathing tubes called trachea instead.
All insects have spiracles. This is how they breathe because they do not have lungs like vertebrates do!

Insects are different from other organisms because they don't have any Lungs . Most organisms on earth have lungs other organisms do not , that is why they are different.

Insects breathe by tracheal structure. The reason insects breathe with their trachea is because they do not have lungs.
insects have trachea breathing systems which means a tunnel from outside reaches every single cell in the insect body. some areas in these tunnels are loose and called air sacs which resemble lungs in function but anatomicly they do not have lungs the way we do.
