Question

what is a stethoscope??????? ​

Answer 1

Answer:

The stethoscope is an acoustic 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, and one or two tubes connected to two earpieces.

Answer 2

The stethoscope is used to check the pulse, breathing rate and the heartbeat. The pulse can be checked by preparing a stethoscope at home. Take a matchstick and a shirt button. Remove the carbon part of the matchstick. Insert the match stick in the button. Place this button on the wrist. The movements of the wrist due to the pulse can be recorded. This pulse is same as the heart beat. Thus, the heartbeat can be recorded by this method.
