Final answer:
The body's cooling system, or thermoregulation, helps maintain a stable body temperature. In desert conditions, sweating and evaporating sweat from the skin helps cool down the body. However, when the body's cooling mechanisms fail, overheating can occur, leading to serious health risks like heat exhaustion and heat stroke.
Step-by-step explanation:
The body's cooling system, also known as thermoregulation, is a process that helps maintain a stable body temperature. In the case of Prosperi attempting to survive in the desert, his body started to sweat in order to cool down. When sweat evaporates from the skin, it takes away heat from the body, thus lowering the internal temperature.
On the other hand, the Hughes family members succumbed to overheating due to their body's inability to regulate temperature effectively. As they were exposed to high temperatures, their body's cooling mechanisms failed to keep up, leading to symptoms such as dizziness, confusion, and fatigue. If not treated promptly, overheating can progress to heat exhaustion and heat stroke, which can be life-threatening.
