Ovary', 'role': 'user'}, {'content': 'Answer: C \nExplanation: White infarcts occur with aerial occlusions in solid organs with end-aerial circulations (e.g., hea, spleen, and kidney), and where tissue density limits the seepage of blood from adjoining patent vascular beds. Infarcts tend to be wedge-shaped, with the occluded vessel at the apex and the organ periphery forming the base ; when the base is a serosal surface, there is often an overlying fibrinous exudate. The margins of acute infarcts typically are indistinct and slightly hemorrhagic; with time, the edges become better defined by a narrow rim of hyperemia attributable to inflammation.
