BiomoleculesListen Planarians lack dedicated respiratory and circulatory systems because their body cavity a pseudocoelom carries out these functions they lack mesoderm as embryos and therefore lack the adult tissues derived from mesoderm Onone of their cells are far removed from the gastrovascular cavity or from the external environment their flame bulbs can carry out respiratory and circulatory functions
