10.2.3 Function of Haemolymph in Transport



  1. Haemolymph is a fluid in the circulatory system of insects.
  2. As blood, haemolymph is the medium of transport that transport substances such as hormone and nutrient to the cells.
  3. For most insects, haemolymph is not used for oxygen transport because these animals respirate directly from their body surfaces to air.
  4. Unlike blood in human’s circulatory system,the haemolymph does not flow in closed blood vessels.
  5. It is pumped out of the heart to fill the spaces between the body cells and then drawn back toward the heart through open-ended pores.
