Speaking of parasites, it is definitely a childhood nightmare for many people, such as as ascariasis, the reason why there is ascariasis, is caused by the ingestion of infectious roundworm eggs, the eggs hatch in the duodenum, the larva produced burrows into the wall of the small intestine, and then migrates to the heart and lungs through blood circulation, from the lungs up the bronchi to the oropharynx is swallowed back into the small intestine, and develops into adults in the small intestine.
Because roundworms have the habit of drilling holes, they will produce severe abdominal pain when they move in the body, and many children are so painful that they lie on the bed and roll, still unable to relieve.
Roundworms belong to a kind of parasite, but the parasite is not only roundworms, such as hookworms, pinworms, tapeworms, schistosomiasis, etc., also belong to parasites, specific to each parasite, and divided into different species.
