Human Body & Health

Why does heatstroke, characterized by a core body temperature exceeding 40°C (104°F), often lead to multi-organ failure, despite the body's inherent thermoregulation mechanisms?

A)Peripheral vasoconstriction enhances oxygen delivery
B)Denatured proteins disrupt cellular functions
C)Sweat gland overactivity maintains electrolyte balance
D)Increased metabolic rate protects organ function

💡 Explanation

Heatstroke overwhelms normal thermoregulation; because excessive heat causes proteins to denature and lose their function, therefore this denaturation disrupts vital cellular processes and damages organ systems, leading to failure, rather than cellular function being protected or oxygen delivery being enhanced.
