What is epiglottis made of?

elastic cartilage
, the epiglottis joins the external ear and the auditory tube of the middle ear in utilizing the structural support and flexibility this type of connective tissue imparts.
What is the composition and function of the epiglottis?
Abstract. The epiglottis, a leaf-shaped cartilaginous supraglottic structure, normally plays a role in
airway protection and prevention of aspiration
. Its composition of elastic cartilage and ligamentous connections allow it to retroflex over and cover the larynx during swallowing.
When swallowing the glottis covers the epiglottis?
air passes through the glottis on its way to the trachea. the epiglottis is an elastic cartilage structure located at the superior portion of the larynx. during swallowing the epiglottis covers
the larynx opening to prevent food and liquids from entering the respiratory tract
.
What does epiglottis look like?
The epiglottis sits at the entrance of the larynx. It is
shaped like a leaf of purslane
and has a free upper part that rests behind the tongue, and a lower stalk (Latin: petiolus). The stalk originates from the back surface of the thyroid cartilage, connected by a thyroepiglottic ligament.

bacterial, fungal or viral infection

What happens if the epiglottis fails to close correctly?
If the epiglottis fails to close correctly,
a person may choke
. The epiglottis is a leaf-shaped flap made of elastic cartilage that covers the opening of the larynx and prevents food or liquids from entering it. Chocking may occur if the epiglottis fails to close, allowing food or liquids to enter the airway.
What is the role of epiglottis during swallowing?
The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis
folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe
and lungs. After swallowing the epiglottis returns to its original upright position.
