体温调节

English | 2009 | ISBN-10: 1607412829 | 392 pages| PDF | 8 MB

Body temperature regulation refers to processes of heating and cooling that an organism uses to control its temperature. Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. This process is one aspect of homeostasis, a dynamic state of stability between an animal's internal environment and its external environment. The maintenance of body temperature in animals is a result of the process of metabolism, by which foodstuffs are converted into protein, carbohydrates, and fat, with the release of energy in the form of heat. Because active muscles metabolize food faster than muscles at rest, giving off more heat in the process, physical activity increases body temperature. This new book provides a great variety of research on human as well as animal body temperature regulation. The principles of thermodynamics pertinent to the exchange of heat energy between the body and its surrounding environment is reviewed. Included also are studies on the effects of diet, body weight, exercise, disease, age and drugs.

体温调节是指一个生物体通过加热和冷却来控制自身温度的过程。体温调节是指生物体能够保持其身体温度在一定范围内，即使周围环境的温度差异很大。这个过程是内环境与外环境之间的动态稳定性状态的一种方面。动物维持其体温的结果是由代谢过程产生的，该过程中食物转化为蛋白质、碳水化合物和脂肪，并以热的形式释放能量。由于活动肌肉比休息时消耗更快的食物，因此在过程中会散发更多的热量，从而使身体温度升高。这本书提供了一系列关于人类以及动物体温调节的研究。书中还介绍了适用于体内环境与周围环境之间进行的热量交换的相关热力学原理。还包括了饮食、体重、运动、疾病、年龄和药物的影响研究。
