After reaching the intestine, worm inside the cyst breaks out the covering and roam freely. It then punctures
the wall of the intestine and enters the adjacent blood pipes and then blood circulation. It then through these
blood pipes reaches various parts of the body especially liver and lung where it makes its permanent abode.
After settling down in any of these favourite places, it stars growing in size and construct for itself an outer
covering for safety and gives birth to hydatid cyst which gradually start increasing in size. When cyst attains
adequate size, the worm feels safe inside the cyst and the start giving birth to new worms who repeat the
same process to become cysts and are now called daughter cysts whose number slowly increases.
