Expert

Verified

In the arthropods respiratory system is open (or lacunar). Blood, also recognized as hemolymph, is pumped by the heart and falls in cavities (or lacunas) draining and irrigating tissues.

Every arthropod has heart. Arachnids and Crustaceans have respiratory pigments. Insects don’t have respiratory pigments because their blood doesn’t carry gases (in them gases reach cells and tissues by the tracheal structures).
