Schistosoma species are blood-dwelling parasites that live in the veins of their hosts, specifically around the intestines or urinary bladder. The adult worms feed on blood and reproduce by laying eggs, which are transported through the bloodstream. This can lead to inflammation and organ damage. The incorrect options—intestine, kidney, and liver—are not the primary habitats of the adult Schistosoma worms, although their presence can impact these organs due to the movement of eggs or other pathological processes.

This option is incorrect. While many parasites inhabit the intestines, Schistosoma specifically targets the blood vessels.

This option is incorrect. Schistosoma does not reside in the kidneys. It is primarily found in the blood vessels.

This option is incorrect. Although Schistosoma eggs may be transported to the liver, the adult worms reside in the blood vessels.

This option is correct. Schistosoma is a parasitic worm that lives in the blood vessels of its host. It can cause significant health problems as the worms lay eggs, which can travel and cause damage to various organs.
