Insect Morphology and Systematicsexcretion and osmoregulationInsect Morphology and Systematicsexcretion and osmoregulation
(maintenance
of favourable osmotic pressure and ionic concentration of body fluid).
The system
responsible for excretion and osmoregulation is referred to as excretory system
and
its activities are performed largely by the Malpighian tubules and hindgut. However in fresh
water insects, haemolymph composition is regulated in response to loss of ions to the
surrounding water, with the help of excretory system and special cells. Special cells are
called
Chloride cells
which are present in the hindgut, capable of absorbing inorganic
ions from the dilute solutions. (e.g. Naids of dragonflies and damselflies).
