2 1. The doctors indicated that Karen had suffered from hyperthermia. What is hyperthermia? Hyperthermia is when the body has an extremely high body temperature without increasing the set point of the thermoregulatory center in the hypothalamus. This can make the metabolic pathways race ahead of others and interrupt coordination leading to death. Forms of hyperthermia include heatstroke and exhaustion. Some symptoms of heat exhaustion include fatigue, thirst, extreme sweating, delirium, and normal or slightly elevated body temperature because of water loss and electrolytes. Other symptoms of heatstroke include no sweating, loss of consciousness, and temperature of 104F. Heat exhaustion can lead to heatstroke which can lead to death 2. How does homeostasis relate to hyperthermia? Homeostasis is the method that the body uses to ensure a stable and reliable internal environment using negative and positive feedback mechanisms. Temperature is one method of the internal environment that is regulated using a feedback mechanism to ensure homeostasis. When a person is diagnosed with hyperthermia it means that the homeostasis mechanism responsible for temperature regulations is not able to maintain homeostasis because of an extreme external factor. 3. How does the application of cool pads and spraying of water on the skin lower body temperature? The application of cool pads and spraying of water on the skin lowers the body temperature by being an external factor and aiding with the regulation of temperature. Body heat is transported to the water on the skin by conduction. As the water on the skin

3 disperses the heat is transferred away from the body. Once this regulation occurs the body can maintain homeostasis. 4. Why did the first aid volunteers spray her with tepid water instead of cold water? The first aid volunteers might have sprayed her with tepid (warm) water instead of cold water to avoid hypothermia since she was already in hyperthermia. Tepid water was used because the temperature was extreme that day. Warm water can increase blood circulation and protect internal organs from damage. By consuming warmer liquids your body will sweat more thus losing more heat and cooling you down quickly. 5. Did the lack of water to drink while she was running help or hinder her situation? Why? The lack or water to drink while Karen was running hindered her situation immensely. She was unable to utilize water to keep her body hydrated and remain at homeostasis. While she ran on that extremely hot day she started to sweat. The sweat evaporated from her skin also removing heat and body fluid. She needed to drink more fluid to replace the fluid she lost while she was sweating during the run. As a result, her body was unable to keep up with usual body functions and operation levels.
