Summary Introduction
To derive: A hypothesis to explain the effect of ice-cold water on the rate at which our body returns back to its normal temperature and also test this hypothesis.
Introduction: The temperature of body rises when someone comes after a long run. Homeostasis is operating under such circumstances for the regulation of temperature in the body. Hypothalamus of the brain maintains the temperature of the body. Homeostasis is mainly dependent on the negative feedback mechanism. When the temperature of the body rises, the hypothalamus senses the increase and reduces body tempearature by activating cooling mechanisms. For example, the secretion of sweat is a cooling mechanism.

A recent newspaper article described a new bottled water that is “super charged” with oxygen. Since the body’s demand for oxygen increases as physical exertion increases, a university athletic coach thought that giving her athletes this oxygenated water would result in better performances. To test this idea, the coach divided her runners up into two groups. During practice, one group was given the super charged, oxygenated water to drink. The other group was given regular water. Both groups completed the same workout and drank the same amount of water (either oxygenated or unoxygenated). At the end of practice, she had all the athletes run 400 meters as fast as they could. She compared the times of the runners who had consumed regular water to those who had consumed the oxygenated water during practice. The coach found that the average time of the oxygenated water drinkers was significantly faster than that of the runners who had consumed regular water during practice. The…

- The range of regulated body temperatures in mammals is about 36 to 40°C , while in birds it is slightly higher, 38 to 42°C, close to the limit compatible with life. Why do you imagine birds maintain higher body temperatures thanmammals? Do you think eagles and hummingbirds maintain the same body temperatures?

Fluid has a high capacity for heat, so it requires a great deal of energy to raise its temperature. B. Warmed fluids from the body’s surface return to the body’s core, thus heating the body. C. Fluid acts as a coolant by increasing the blood flow from the warm body core to the peripheral tissue, thus cooling the body. D. Fluid is evaporated as sweat from the skin’s surface, thus cooling the body.arrow_forward
- Imagine you worked in a physical therapy center that uses swimming pools to aid recovery for patients who had leg surgeries. If you wanted your clients to comfortably swim in a pool that was 76 °F, what kind of shower would you have them rinse off with before enter the pool?

Predict what would happen to the metabolic rate of the mouse if you decreased the temperature (You can make this prediction with text or with lines on your graph). Support your prediction with evidence about endotherms and ectotherms. (Hint: Think about what happens to your body when you get hot or cold.)arrow_forwardEndothermy and Ectothermy are two strategies that organisms use to generate or maintain their internal body temperature. An ectotherm is an organism that derives very little of its body temperature internally, and relies on the environment for heat. An endotherm is an organism that maintains its own body at a metabolically favorable temperature by internal means. Question: How does temperature affect endotherms and ectotherms differently?
