Explanation:

slight bend or kink in the capillary tube of the clinical thermometer near the bulb ensures that the mercury does not move back into the bulb when the thermometer is taken out of a person's mouth for reading.The clinical thermometer has a kink (or constriction) in its tube to prevent the back flow of mercury into the bulb
