Question

In humans, sound is produced by:
A. larynx.
B. windpipe.
C. vocal cords.
D. lungs.

Answer 1

Hint: In the human body the muscles vibrate and the air passing through the muscles produce the sound. It is produced from an organ present in the neck which controls pitch and volume of sound.

Step by step solution:
We will consider all the options one by one and then make conclusions which option is the correct answer and also we will discuss the given options.
Let us see first option,
Larynx,
Larynx is the part of the human body which controls the production of sound used for speech. Larynx is also known as the voice box in the human body. It also helps the airway from choking in the throat.
Let us see second option,
Windpipe,
Windpipe is also known as trachea in the human body, it is the part of the respiratory system. The function of windpipe is to allow the passage of air from nose to the lungs and also from lungs towards the nose, it provides human body oxygen and helps in removal of carbon dioxide.
Let us see third option,
Vocal cords,
Vocal cords provide air to the larynx. Vocal cord vibrates so that air is provided by the lungs into the larynx which helps in production of sound.
Let us see the fourth option.
Lungs,
Lungs are the part of the respiratory system; they are sites where the exchange of gases takes place. The air coming into lungs has oxygen which gets into the blood; also the metabolism waste i.e. carbon dioxide leaves the blood in the lungs.

After considering all the options the correct answer is option A, larynx helps the human body to produce sound.

Note: Students should not get confused in the larynx and vocal cords, both of them have different functions in the human body. Vocal cords help in sound production as it provides air into the larynx by vibrating and the larynx is producing the sound, so the correct answer would be larynx.
