disease with almost 1 billion cases consistently.

from sullied soil.



 Ascaris lumbricoides is one of the dirt sent helminths, other most house
soil-communicated helminths are whipworm (Trichuris trichiura), and
hookworm (Ancylostoma duodenale and Necator americanus.



 On ingestion, the embryonated eggs hatch in the stomach and duodenum,
where the hatchlings effectively enter the digestive wall.

Hatchlings inside the eggs go through one or perhaps two sheds before
entrance of the digestive wall.

 From the right heart, they are conveyed into the pneumonic
dissemination, where they are sifted through by the vessels.

move through the bronchi until they arrive at the windpipe and pharynx,
and then, at that point, are gulped.
