Give the Life Cycle in Ascaris Lumbricoides
ingestion of embryonated ova —- in the small intestine, —- larvae will emerge from the egg —- the larva will undergo hepatic or lung migration for further development then return to the small intestine where it will become adult —- the female adult will lay egg which will be passed on stool —- where it needs soil to be embryonated and taken up by man to repeat the cycle.
