Respiration in Cockroach - BYJUS Respiration in Cockroach In cockroach, respiration occurs through spiracles – a small opening on the sides of its body When air through external openings, enters into its respiratory system, spiracles serve as muscular valves paving way to the internal respiratory system The respiratory organ of cockroach is referred to as tracheae

Insect groups of animals have spiracles and tracheae for breathing and respiration The tracheal framework is an intricate and profoundly powerful gas trade framework comprised of stretching versatile air tubes or tracheae that permits bugs to relax
Breathing in Lower Organisms - BYJUS Breathing in Insects The body of the insects is covered with holes called spiracles The oxygen enters these holes and reaches the trachea which helps them to circulate throughout the body The carbon dioxide is carried by the trachea and expelled out through the spiracles Also Read: Morphology and Anatomy of Cockroach Breathing in Frogs
