Question

Normal temperature of human body is considered to be
A) 98.4 degree Fahrenheit
B) 98.2 degree Fahrenheit
C) 90.4 degree Fahrenheit
D) 98.6 degree Fahrenheit

Answer 1

Hint: Normal body temperature is the optimum temperature of the body at which all the physiological activities take place. The normal temperature is maintained by the central nervous system. The temperature beyond normal body temperature is considered as fever. Degree Fahrenheit is the unit used to measure temperature.

Complete answer:
Human beings are warm blooded. It means that they maintain a normal body temperature which is constant at which the body is in thermal equilibrium state. At this optimum temperature, all the hormones, enzymes are active and perform optimum physiological reactions. The normal body temperature lies in between 97.7-99.5 degree Fahrenheit.

The temperature of the human body varies with respect to age, gender, exertion level, health conditions etc. The difference in temperature is seen in case of consciousness and unconscious state. The temperature of 98.6degree Fahrenheit is considered as normal body temperature. This temperature is adjusted by the thermoregulation centre present in the central nervous system. Any temperature above 99 degree

Fahrenheit is considered as fever. Fever is considered as a state of illness in which the physiological reactions are not carried out properly in our body. Certain medications are prescribed so as to bring down the body temperature to the normal state.

Hence the correct answer is option ‘D’.

Note: A clinical thermometer is used to measure the body temperature. Degree Celsius is another unit used to measure body temperature. 98.6degree Fahrenheit is equivalent to 37 degree Celsius. The temperature can be recorded by placing the thermometer in the forehead, mouth, rectum, armpit or ear
