<b>Hyperthermia-induced sudden death: Morphological insights from the lung and heart in an experimental study of Wistar rats</b>

While some organs exhibit greater tolerance to heat stroke than other organs, most organs show similar alterations characterized by capillary dilation, vascular pathway disruption, and extravasation. The extent of pathological changes in myocardial and lung tissue intensified with higher temperatures and longer exposure durations to elevated WT. However, the progression of morphological alterations in cardiomyocytes did not demonstrate marked significance, likely because of the brief exposure period. This short duration may limit the detection of subcellular changes when using hematoxylin-eosin staining.
