Difference Between Glottis and Epiglottis

Glottis and epiglottis situated within the pharynx protect the airway while swallowing food. Glottis is the narrowest part of the larynx and opens into the airway. Vocal cords make lateral borders of it. Epiglottis, a leaf-shaped cartilaginous flap, prevents the food from entering the airway passage of the respiratory system while swallowing. The larynx muscles have the tendency to contract while swallowing which causes an upward movement of the glottis and downward movement of the epiglottis.


The human systema respiratorium consists of a gaggle of organs and tissues that help us to breathe. Lungs are the first organs of the systema respiratorium which help within the exchange of gases. The other main parts of this technique include a series of airways for air passages, blood vessels, and therefore the muscles that facilitate breathing.


Features of the Human Respiratory System

The system respiratory in humans has the subsequent important features.

  • The energy is generated by the breakdown of glucose molecules in all living cells of the human body.

  • Oxygen is inhaled and is transported to varied parts and are utilized in the method of burning food particles (breaking down of glucose molecules) at the cellular level during a series of chemical reactions.

  • The obtained glucose molecules are used for discharging energy within the sort of ATP- ATP molecules by the physical body to fulfil essential life processes.


Respiratory Tract

The respiratory tract in humans is made up of the following parts:

  • External Nostrils – For the intake of air.

  • Nasal Chamber – Is jammed with hair and mucus so that it filters the air and removes the dust and dirt.

  • Pharynx – It's a passage behind the nasal chamber and is the common passageway for both air and food.

  • Larynx – Also known as the soundbox as it helps in the generation of sound and thus helps us in communicating.

  • Epiglottis – It's a flap-like structure that covers the glottis and prevents the entry of food into the windpipe.

  • Trachea – It's an extended tube passing through the mid-thoracic cavity.

  • Bronchi – The trachea divides into left and right bronchi.

  • Bronchioles – When each bronchus is further divided into finer channels, that is known as the Bronchioles. 

  • Alveoli – The bronchioles find yourself into the balloon-like structures referred to as the alveoli

  • Lungs – We've a pair of lungs, which are sac-like structures and covered by a double-layered membrane referred to as pleura.


Glottis vs Epiglottis

Glottis 

Epiglottis

Glottis opens into the airway.

Epiglottis forms the superior border of the glottis.

Size of the glottis is liable for the voice type.

Size of the epiglottis is not responsible for the voice type.

While swallowing glottis moves upward.

While swallowing epiglottis moves downwards.


Glottis opens into the windpipe and is responsible for the production of sound. While the epiglottis may be a cartilaginous flap on top of the glottis that forestalls the food from getting into the larynx. The main difference between glottis and epiglottis is their function and therefore the structure.

FAQ (Frequently Asked Questions)

Q1. Where is Glottis and Epiglottis Situated?

Ans - Glottis and epiglottis situated within the pharynx protect the airway while swallowing food. Glottis is the narrowest part of the larynx and opens into the airway. Vocal cords make lateral borders of it. Epiglottis, a leaf-shaped cartilaginous flap, prevents the food from entering the airway passage of the respiratory system while swallowing. The larynx muscles have the tendency to contract while swallowing which causes an upward movement of the glottis and downward movement of the epiglottis.
