Question

What is the leaf-shaped piece of cartilage that closes over the larynx when you swallow?

Answer 1

The leaf-shaped piece of cartilage that closes over the larynx when you swallow is called the epiglottis. The epiglottis is a flexible flap of cartilage located at the base of the tongue, above the larynx (voice box). Its primary function is to prevent food and liquid from entering the airway (trachea) when swallowing.

During swallowing, the epiglottis folds backward to cover the opening of the larynx, forming a protective seal. This prevents food and liquid from entering the respiratory pathway and ensures that they are directed towards the esophagus and into the digestive system.

The epiglottis plays a crucial role in protecting the airway during swallowing, allowing us to eat and drink without the risk of choking or aspiration. After swallowing is complete, the epiglottis returns to its upright position, allowing air to pass freely through the larynx for breathing and speaking.

Answer 2

The epiglottis is the leaf-shaped piece of cartilage that seals the larynx to prevent food and liquid from entering the airway during swallowing. It is a flexible structure attached to the thyroid cartilage.

Step-by-step explanation:

The leaf-shaped piece of cartilage that closes over the larynx when you swallow is known as the epiglottis. This very flexible piece of elastic cartilage is attached to the thyroid cartilage and is a part of the larynx. During the act of swallowing, the epiglottis swings down to cover the opening of the trachea, effectively preventing food and beverages from entering the airway and directing them towards the esophagus.

The larynx includes other structures, such as the thyroid cartilage, which features the laryngeal prominence, or "Adam's apple," and the cricoid cartilage. Vocal cords, consisting of vestibular folds (false vocal cords) and true vocal cords, are also found within the larynx. The movements of these components during swallowing ensure that the respiratory pathway is sealed and the food is guided correctly into the gastrointestinal tract.
