A simple diagram to show the difference between the teguments of free-living and parasitic flatworms: a. shows the syncytial epithelial tegument found in parasitic flatworms, such as F. hepatica. b. shows the multicellular, nonsyncytial, epithelia, found in nonparasitic, free-living flatworms.
Diagram of the main organ systems of F. hepatica throughout the progressive life stages of the fluke (1938). A - egg; B - miracidium; C - sporocyst; D
