Glottis and Epiglottis

The fundamental distinction between the glottis and the epiglottis is that the glottis is the opening between the vocal folds that opens into the airway, while the epiglottis is the glottis’ superior border. In addition, the size of the glottis determines the voice type, whereas the size of the epiglottis has no bearing on the voice type.

The glottis and epiglottis are two structures found at the opening of the windpipe in the larynx. Both are in charge of the creation of sound.

Glottis : 

The glottis is the aperture in the larynx between the vocal cords. It is the passageway through which air enters and exits the lungs.

Epiglottis : 

During swallowing, the epiglottis is a thin, leaf-like cartilage structure that protects the aperture of the larynx (voice box). The epiglottis flaps up to allow food to pass through the esophagus, then flips back down to cover the larynx, preventing food and liquid from entering the windpipe and causing choking.

Difference between Glottis and Epiglottis : 

The Human Respiratory System’s Characteristics : 

The human respiratory system has the following major characteristics. 

• In all living cells of the human body, energy is generated through the breakdown of glucose molecules. 

• Oxygen is inhaled and delivered to various regions of the body, where it is used in a sequence of chemical processes at the cellular level to burn food particles (break down glucose molecules). 

• The acquired glucose molecules are utilized by the physical body to discharge energy within the form of ATP- ATP molecules in order to carry out important living operations.

Similarities :

• In the larynx, the glottis and epiglottis are two anatomical structures.

• Both play a role in the creation of sound.

Their Roles :

• The glottis is the entry into the windpipe, while the epiglottis is the glottis’ superior border.

• The size of the glottis determines the voice type, whereas the size of the epiglottis has no bearing on the voice type.

• During swallowing, the glottis moves higher, while the epiglottis goes downwards.

• The glottis is in charge of sound generation, while the epiglottis keeps food from entering the larynx.

Parts of Respiratory Tract :

1. Pharynx : The pharynx, often known as the throat, is a part of both the respiratory and digestive systems. It transports air, food, and liquids from the nose and mouth to the stomach. Common ailments, such as sore throat and tonsillitis, affect the pharynx.

2. Larynx : In your body, your larynx serves three primary functions: Breathing. Making vocal noises. Food and other particles are kept out of your trachea, lungs, and other parts of your respiratory system.

3. Nasal Chamber : The nasal cavity is located above the bone that forms the roof of the mouth and curves down to connect the throat at the rear. The nasal passageways are separated into two portions. During breathing, air passes via these channels. 

4. Trachea : The primary purpose of your trachea is to transport air into and out of your lungs. It provides a reliable channel for oxygen to enter your body because it is a rigid, flexible tube.

5. Bronchi : Their job is to warm, moisturize, and clean the inhaled air before distributing it to the lung’s gas-exchanging zone. They are lined by ciliated cells and many interspersed mucus-secreting goblet cells, which are typical of the respiratory epithelium.

6. Alveoli : They are responsible for transporting oxygen and carbon dioxide (CO2) molecules into and out of your bloodstream.

7. Lungs : Oxygen enters your bloodstream and travels throughout your body. Oxygen is exchanged for a waste gas called carbon dioxide at each cell in your body. 

Conclusion :

The glottis is the aperture into the windpipe that allows sound to be produced. The epiglottis, on the other hand, is a cartilaginous flap on top of the glottis that prevents food from entering the larynx. The structure and function of the glottis and epiglottis differ significantly.
