Introduction

I often wonder , what's the most unique thing about a doctor that differentiates him from others in a hospital . Then I thought about the most obvious instrument that every doctor has , and thats the stethoscope that is wrapped around every doctor's neck like a snake .

Stethoscope

The stethoscope is a hearable medical device used to listen internal sounds of our complex body , it has a small disc-shaped echoer that is placed against the chest . It also has two seperate tubes leading to two seperate earphones like structure through which a doctor is able to hear the choas going inside us . Moreover , the lub and dub sound of heart , arteries blood flow and breathing from lungs can also be heard through this . It can also be used to measure blood pressure in correlation with sphygomanometer . This is one of the most important tool that a medical professional can own . Beside being in a basic color of black and silver ,to attract patients it comes in competitive wide range of colors and styles too .
