Final answer:
Fasciola hepatica, or the liver fluke, resides in the liver of bovines, specifically within the bile ducts, and is the cause of fascioliasis.
Step-by-step explanation:
In bovines, Fasciola hepatica, commonly known as the liver fluke, primarily resides in the liver. This parasitic flatworm infects the bile ducts within the liver. By contrast, the intestinal flukes, such as Fasciolopsis buski, are found in the intestines.
The importance of understanding where certain parasites, like the liver fluke, prefer to inhabit within their host's body sheds light on the pathology of the disease they cause and the necessary treatments. Knowing Fasciola hepatica opts for the liver rather than other parts of the digestive system, such as the abomasum or the small intestine, ensures accurate diagnosis and proper management of the resulting condition, fascioliasis.
