Accepted Answer

The thermometer used for measuring the temperature of the human body is called a clinical thermometer.

The construction of a clinical thermometer is the same as that of a laboratory thermometer. The only difference is that there is a slight bend in the stem just above the bulb. This bend (kink) prevents the movement of mercury back into the bulb when the thermometer is taken out of a person’s mouth. The clinical thermometer has a range from $35^{°} C$ (lower fixed point) to $42^{°} C$ (upper fixed point) because the temperature of a human body never goes beyond these limits. The normal temperature of a human body is $37 ° C$ or $98.6 ° F$ . Expansion of matter due to heat is the working principle of a clinical thermometer.
