Vedclass · Answer

(A) In $Periplaneta$ (cockroach),the respiratory system consists of a network of trachea that open through $10$ pairs of small holes called spiracles present on the lateral side of the body.These thin branching tubes (tracheal tubes) carry oxygen from the air directly to all the tissues of the body.Since the oxygen is supplied directly to the tissues via the tracheal system,the blood does not need to transport respiratory gases.Therefore,the blood of $Periplaneta$ lacks any respiratory pigment like haemoglobin.
