  • Function of Haemolymph in Transport
    • Haemolymph: circulating blood-like fluid found in some invertebrates with open circulatory systems.
      • Not confined to vessels only
    • Bathes the tissues and internal organs directly
    • Nutrients eg. digested food substances, hormones diffuse from haemolymph into cells.
    • Waste products diffuse out from the cells into the surrounding haemolymph
    • Insects - their tubular hearts pump the haemolymph into fluid-filled spaces: haemocoel.
