Circulatory systems contain all of the following except (not all circularity systems contain all of these)? O Valves O Respiratory pigments O Circulatory fluid O Pump(s) Tubes ✓

Describe the tracheal system of a typical insect and explain why it can function efficiently without oxygen-carrying pigments in the hemo-lymph. Why would a tracheal system not be suitable for humans?

Discuss the Single and double circulation in animals

Neither cnidarians nor turbellarians possess a circulatory system. For most large, active animals, this would pose a (fatal) problem. Describe and discuss the features of large active cnidarians ands turbellarians that allow them to respire, nourish their cells, and excrete despite the absence of a conventional circulatory system.
