Description:This magnified view reveals four Schistosoma mansoni trematodes. At the far left is a pair of worms, where the thinner female is cradled inside the thicker male worm's gynecophoral canal. In the center is a single thin female worm, and at far right is the more robust, thicker male S. mansoni.
Adult worms in humans reside in the mesenteric venules in various locations, which at times seem to be specific for each species, For instance, S. mansoni occurs more often in the superior mesenteric veins draining the large intestine.
