STETHOSCOPE

DESCRIPTION:

The stethoscope is a medical device for auscultation, or listening to internal sounds of an animal or human body.

It typically has a small disc-shaped resonator that is placed against the skin, with either one or two tubes connected to two earpieces.

A stethoscope can be used to listen to the sounds made by the heart, lungs or intestines, as well as blood flow in arteries and veins.

In combination with a manual spygmomanometer, it is commonly used when measuring blood pressure.
