Which instrument is used to listen to sounds inside the body, such as the heartbeat?

Explanation:
Listening to sounds inside the body is done with a stethoscope, an instrument designed for auscultation. It transmits body sounds—like the heartbeat, breathing, and sometimes bowel sounds—through a chest piece and tubing to your ears so you can hear them clearly. This is how you assess heart rate, rhythm, and other internal noises. The otoscope is used to look into the ears, the sphygmomanometer measures blood pressure with a cuff, and the thermometer measures temperature. So, for hearing the heartbeat, the stethoscope is the appropriate tool.
