Answer

The correct answer is option 'D', the epiglottis is not a vestigial organ in humans.

The term 'vestigial' refers to organs or structures that have lost their original function throughout the course of evolution. These organs may have had a purpose in ancestral species but have become reduced or non-functional in modern organisms. However, the epiglottis is not considered a vestigial organ because it still serves an important function in humans.

The epiglottis is a flap of cartilage located at the base of the tongue, just above the larynx (voice box). Its primary function is to prevent food and liquids from entering the airway during swallowing. When you swallow, the epiglottis moves downward, covering the opening of the larynx and directing the food or liquid towards the esophagus, which leads to the stomach. This action helps to prevent choking and ensures that food and fluids go down the correct pathway.

The role of the epiglottis is crucial for protecting the respiratory system. Without the epiglottis, there would be a higher risk of aspiration, which is when food or liquid enters the lungs instead of the stomach. Aspiration can lead to serious respiratory complications such as pneumonia.

Although the epiglottis may not be as prominent or noticeable as some other organs, it is definitely not vestigial. It continues to play a significant role in the normal functioning of the human body.

In summary, the epiglottis is not a vestigial organ in humans. It serves an important function in preventing food and liquids from entering the airway during swallowing, thus protecting the respiratory system.

Answer

Vestigial organs are degenerate, non-functional and rudimentary organs correspond to fully developed and functional organs of related organism. Third molar (wisdom teeth), plica semilunaris and pyramidalis muscles are vestigial organs. Epiglottis is not a vestigial organ in man. Epiglottis is the structure that prevents the entry of food into respiratory tract during swallowing in man.
