Question

a 23-year-old –male was riding his road bike in 100- degree heat, when he suddenly became nauseated and weak. He called 911 from his cell phone. When the ambulance cam, the paramedics started intravenous therapy for severe dehydration. Explain the critical role of water to maintain homeostasis?

Answer 1

Well, water is a large part of homeostasis and is extremely important. So, here you are talking of dehydration which is the removal of water from his body. So, now we have a relative defiencient amount of water in his system and his symptoms are getting worse and with the more loss continue to become more severe. So, now his body is signaling to say hey, something is wrong. With those signals from his body it begins to activate more responses to attempt to fix the problem and to compensate. Now, you could see him breathe faster and his heart beat faster because again, it is trying to fix the problem of the decreased plasma volume and blood pressure from the loss of water. In addition to this though, he is starting to get hotter and hotter because after a while he will not be able to sweat anymore to cool his body temperature. Therefor, he needed an iv started to increase his volume and to activate natural compensation to cool his body down again.
