A thermometer is a small, sealed glass tube filled with liquid mercury. The mercury expands easily with temperature, so it can be used to accurately gauge a body's temperature.
As for a stethoscope... hold out your hand? [ She'll place the metal portion of the stethoscope into his hand, if offered. ] The flat ends magnify sounds and send them up through the tubing, where I'll have ends in my ears to listen. It's to hear heartbeats, blood flow, and breathing for any irregularities.
