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.

∙ 14y agoInsects, including cockroaches, do not normally have hearts or a vascular system since their "blood" (which more resembles goo) is distributed throughout the body and delivers nutrients and oxygen without the need of a "pump". Also, their ganglia (brain and nervous system) is often decentralized so that the part that controls a particular body function - for instance, the movement of the legs - is located near that body part, rather than in a centralized brain.
As unattractive as it might seem, a cockroach, therefore, can live without its head until it starves to death, since the head does not control the rest of the body functions, but serves to contain sensory organs and the mandibles (mouth) through which the animal derives nutrition.
