發(fā)熱fever

對于醫(yī)學(xué)生來說，進(jìn)行醫(yī)學(xué)英語學(xué)習(xí)是非常有必要的，因為在工作中會涉及到很多國內(nèi)外的最新醫(yī)學(xué)信息。下面是小編整理的發(fā)熱fever的資料，希望對你有所幫助！

發(fā)熱fever

　　Fever

　　發(fā)熱

　　Fever is a physiologic state in which the body temperature is elevated above the individual’s normal temperature, usually over over 100°F (37.8°C).

　　發(fā)熱是指體溫升高超過個體正常溫度的一種生理狀態(tài)，通常指華氏100度或攝氏37.8度以上。

　　A healthy person's body temperature fluctuates between 97°F (36.1°C) and 100°F (37.8°C), with the average being 98.6°F (37°C). The body maintains stability within this range by balancing the heat produced by the metabolism with the heat lost to the environment. The "thermostat" that controls this process is located in the hypothalamus, a small structure located deep within the brain. The nervous system constantly relays information about the body's temperature to the thermostat, which in turn activates different physical responses designed to cool or warm the body, depending on the circumstances. A fever occurs when the thermostat resets at a higher temperature, primarily in response to an infection. form www.med66.com

　　健康者體溫波動范圍為97°F (36.1°C)至100°F (37.8°C)，平均98.6°F (37°C)。機(jī)體通過自身代謝產(chǎn)生的熱量與環(huán)境消耗熱量之間的平衡來使體溫穩(wěn)定在該范圍內(nèi)。控制該過程的“調(diào)溫器”位于下丘腦，大腦深處。神經(jīng)系統(tǒng)不斷向這個“調(diào)溫器”傳遞機(jī)體溫度信息，再由“調(diào)溫器”根據(jù)不同情況，激活各種生理反應(yīng)，冷卻或加熱機(jī)體。當(dāng)“調(diào)溫器”設(shè)置處于較高端時，就會出現(xiàn)發(fā)熱現(xiàn)象，它主要是對感染所作的一種反應(yīng)。
