Answer 1

Hint: The stethoscope is an auditory medical instrument for the auscultation or listening to an animal or human body's internal sounds. A phonendoscope is called a stethoscope that intensifies auscultatory sounds.

Complete Answer:
It normally has a small resonator that is mounted against the skin in the form of a disc, and one or two tubes connected to two earpieces. The noises made by the heart , lungs or intestines, as well as blood pressure through the arteries and veins, can be listened to using a stethoscope. It is widely used for calculating blood pressure, in conjunction with the manual sphygmomanometer.

The 7 Stethoscope Sections:
1. Chest Piece: "Stethos" means "chest," so the logical place to begin is here. The chestpiece is the section of the instrument you carry against the patient's body.

2. Diaphragms: It can be double-sided or single-sided. Typically, a two-sided chestpiece will have a diaphragm on one side and a deep cup-shaped side called a bell. Typically, both single-sided and double-sided parts would have a flexible ring called a chill ring that covers them, helping to make an airtight seal and buffer the patient against the part's coldness.

3. The Stem: What links the chestpiece to the tubing.

4. Acoustic tubes: The hollow rubber-like tubes are the acoustic tubes that connect the chestpiece to the ear tubes.

5. Headset: This is usually the stethoscope 's metal part.

6. Ear tubes: Ear tubes are hollow metal tubes that are attached on one end to the acoustic tubes and on the other to the earpieces.

7. Earpieces: The little tips on the ends of the ear tubes that fit into your ears are earpieces. An option of hard plastic or soft silicone earpieces may be required for certain stethoscopes.

8. Bell: The chest-piece 's smaller circular end.



- Metals: Made of metal, the chest piece and the ear tubes are. They are most commonly made of aluminium or stainless steel, but titanium or zinc may also be the chest component, and brass can be the ear tubes.

- Nonmetals: All the soft sections of a stethoscope have historically been made of rubber, but they can now be made of plastic, silicone or PVC with the advent of new materials. Most frequently, earpieces are made of silicone or hard plastic. Today's acoustic tubes are either made of neoprene or PVC.

The correct answer is option (C) Rubber tube.

Note: The stethoscope at the Necker-Enfants Malades Hospital in Paris was invented in France in 1816 by René Laennec. This consisted of a wooden tube and was monumental. Laennec invented the stethoscope because he was not comfortable putting his ear directly on the chest of a woman to listen to her heart. He noted that, without needing physical contact, a rolled piece of paper, positioned between the chest of the patient and his ear, could intensify heart sounds.
