Rezime

Paraziti su živa bića koja se za vreme jednog dela života ili tokom celog života, hrane i žive na
raĉun drugih živih bića. U parazitske pljosnate crve spadaju i metlji i pantljiĉare. Kod ĉoveka
uglavnom parazitiraju kao endoparaziti (parazitiraju u unutrašnjosti ĉovekovog organizma). Cilj
istraživanja je otkrivanje najvećih ĉovekovih parazitskih neprijatelja klasa Trematodes (metilji) i
Cestodes (pantljiĉare). Analizirane su najĉešće i najpoznatije vrste. Istraživanje je pokazalo da
najveći broj vrsta klase Trematodes parazitira u crevnom traktu, žuĉnom kanalu, mada neki žive i
u krvnim sudovima i celomu. Vrste klase Cestodes parazitiraju u tankom crevu i žuĉnom kanalu
jetre. Ĉovek ih u organizam unese najĉešće preko prljavih ruku ili neopranog voća i povrća na
kojima se nalaze već uĉaurene larve.

Kljuĉne reĉi: Tanko crevo, jetra, celom, endoparaziti, Trematodes, Cestodes.

Summary

Parasites are living beings that during one part of life and throughout life, food and live at the
expense of other living beings. The parasitic flat worms are liver flukes and tapeworms. In
humans, they parasite mainly as endoparasites (parasites inside the human body). The survey
aim is to discover the man's greatest parasitic enemy in class of Trematodes (flukes) and
Cestodes (tapeworms). We analyzed the most common and best known species. Research has
shown that most types of class Trematodes parasite in the intestinal tract, bile ducts, although
some live in blood vessels and over. Types of Class Cestodes parasite in the small intestine and
biliary cirrhosis. A man usually enters them in organism through dirty hands or unwashed fruits
and vegetables where are already cocooned larvae.
