Larynx vs. Trachea — What's the Difference?

The larynx (), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter.

The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi.

The part of the respiratory tract between the pharynx and the trachea, having walls of cartilage and muscle and containing the vocal cords enveloped in folds of mucous membrane.

(Anatomy) A thin-walled, cartilaginous tube descending from the larynx to the bronchi and carrying air to the lungs. Also called windpipe.

A hollow muscular organ of the neck of mammals situated just below where the tract of the pharynx splits into the trachea and the oesophagus. It is involved in breath control and protection of the trachea, and, because it houses the vocal cords, sound production.

(Zoology) One of the internal respiratory tubes of insects and some other terrestrial arthropods, which are connected to the spiracles and are used for gas exchange.

The expanded upper end of the windpipe or trachea, connected with the hyoid bone or cartilage. It contains the vocal cords, which produce the voice by their vibrations, when they are stretched and a current of air passes between them. The larynx is connected with the pharynx by an opening, the glottis, which, in mammals, is protected by a lidlike epiglottis.

(Botany) A tracheary element.

A cartilaginous structure at the top of the trachea; contains elastic vocal cords that are the source of the vocal tone in speech

(anatomy) A thin-walled, cartilaginous tube connecting the larynx to the bronchi.

The xylem vessel.

(entomology) One of the cuticle-lined primary tubes in the respiratory system of an insect, which extend throughout its body.

The windpipe. See Illust. of Lung.

One of the respiratory tubes of insects and arachnids.

One of the large cells in woody tissue which have spiral, annular, or other markings, and are connected longitudinally so as to form continuous ducts.

Membranous tube with cartilaginous rings that conveys inhaled air from the larynx to the bronchi

One of the tubules forming the respiratory system of most insects and many arachnids
