Where do Schistosomes, a type of fluke, notably reside within the human host?

Answer

In blood vessels.

Flukes, classified within the phylum Platyhelminthes, encompass several types, including trematodes like the blood flukes responsible for schistosomiasis (bilharzia). A crucial detail regarding these parasites is their specific habitat within the definitive human host: unlike many other helminths that inhabit the intestinal lumen, schistosomes establish themselves and reside within the host's blood vessels. This unique location dictates the resulting pathology and is associated with infection transmission routes involving contaminated water or aquatic plants.
