What is the normal temperature of the human body? How is it indicated in a clinical thermometer?
उत्तर
Normal temperature of a human body is 37°C or 98.6 °F.
To measure the temperature of a patient’s body, its bulb is kept either below the tongue or under the arm’s pit of the patient for about a minute. Then the thermometer is taken out and its reading is noted. When the temperature of a patient’s body is above 37°C, he is said to suffer from fever.
