Because living humans are homeotherms.
A clinical thermometer, this type of thermometer is sensitive to very small changes in temperature but is able to measure temperatures only within a few degrees of normal body temperature (thirty seven degrees celsius).

The small cross section of a clinical thermometer is there to reduce the amount needed of the toxic mercury to as little as possible. Mercury is less used nowadays, as breakages were likely due to the violent shaking needed to 'reset' the thermometer.
Because clinical thermometer have a very small range. (20 to 45 degrees Celsius at most) and if placed in boiling water, the water being 100 degrees will cause damage to the thermometer.
A sensitive thermometer with an adjustable range so that small differences in temperature can be measured.
Clinical thermometers, also known as medical thermometers, are used for measuring human body temperature. They have kinks at one end which prevent the fluid from flowing back before the readings have been taken. They offer accurate and easy-to-read recordings, in addition they are easy to clean, to carry around and to store.
A thermometer used to measure body temperature is extremely accurate over an extremely small range of temperatures. It will give the temperature to the tenth of a degree. A laboratory thermometer does not have the partial degree separations but gives the temperature over a much wider range of temperatures.

Definition:It is an instrument used to measure body temperature.Diagram:Description:It is a small glass thermometer designed for clinical use in humans or animals. Designed with a narrowing small glass above the bulb so that the mercury column stays in position when the instrument is removed from the body. It is carefully calibrated at the time of manufacturing. Now a days mercury thermometer not used because it can break, spilling mercury posing a risk of human or animal health. they can be inserted in the month, armpit, anus or even attached to the forehead depending on the design.
It's a liquid over a fair range of temperatures and it expands and contracts noticeably with small changes in temperature.

A wrongly calibrated instrument is one that shows the wrong measurement. For example, alcohol in a thermometer rises with temperature; but the exact marks for 0 degrees, 10 degrees, ... 100 degrees (for example) may be wrongly placed, so that, when the temperature really is 30 degrees, the thermometer only shows 28 degrees (for example). Any instrument will have some error of this type, but the idea of calibration is to keep this kind of error reasonably small.A wrongly calibrated instrument is one that shows the wrong measurement.
