Question

how did cockroach breath

Answer 1

Hey...
Like other insects, cockroaches breathe through a system of tubes called tracheae which are attached to openings called spiracles on all body segments. When the carbon dioxide level in the insect rises high enough, valves on the spiracles open and carbon dioxide diffuses out and oxygen diffuses in.

Hope it helps..!!

Answer 2

Cockroach will breath through spiracles.
