Q. What is the life cycle of ascaris?

The Adult ascaris that live within the human intestine can release up to 200 thousand eggs a day. The eggs are eradicating with human feces and mature in the environment under some heat and moisture conditions. The Humans may ingest mature eggs through food contaminated by human feces or through bad hygienic habits. The eggs over again inside the human intestine release larvae that cross the enteric mucosa and gain the circulation reaching the lungs. In lungs the larva mature as well as go to the airway and to the pharynx when they are then swallowed within the gut the larvae develop into adult worms.
