Hint: A cockroach is an insect, it has a dense array of a network of air tubes found in the internal system. When oxygen rich blood enters the body of the cockroach they respire through the small openings called spiracles into these air tubes, it diffuses into various tissues and cells of the body.

Complete answer:-
To answer this question you must know the breathing system of cockroaches.
Breathing is a process of inhaling and exhaling the gases between the cell and the environment.
Cockroaches are not dependent on their mouth or windpipe for breathing. Cockroaches breathe just like any other insect because they do not have lungs like other humans and mammals. They breathe through a series of openings along both sides of the body called spiracles. These spiracles lead to a branching of smaller and smaller air tubes called tracheae, a dense array of networks of air tubes. It is only found in insects only. It allows the oxygen rich blood into these tubes,through the diffusion it reaches every cell of the body.
Cockroaches are not dependent on the blood for transportation of oxygen.

Thus cockroaches breath with the help of an air tube called tracheae.

Note:-
cockroaches are a very common insect that can hold their breath for up to 7 times, unfortunately it's also very resistant. It can survive 7 days without a head. It can eat any organic matter including even wax and it can survive 500 times more radiation than humans but, despite all that, it breathes using trachea, just like other insects.
