Definition
- Noun:
- The windpipe: The main airway that carries inhaled air from the larynx (voice box) to the bronchi and lungs in vertebrates, including humans. It is a tube reinforced by rings of cartilage.
- A respiratory tubule in arthropods: One of the fine, air-conducting tubes that form the respiratory system in most insects and many arachnids (e.g., spiders).
Usage
- The word "trachea" is a countable noun. Its standard plural form is tracheae (pronounced /trəˈkiːiː/ or /ˈtreɪkiˌiː/), especially in scientific contexts. The plural tracheas is also acceptable in general use.
- It is primarily used in medical, biological, and anatomical contexts.
Examples
- Human/Vertebrate Anatomy:
- During the procedure, a tube was inserted into the patient's trachea to help him breathe.
- The trachea branches into two smaller tubes called the bronchi.
- Zoology/Entomology:
- Oxygen is delivered directly to the tissues through a network of tracheae in insects.
- The spider's tracheal system is highly efficient for its size.
Advanced Usage
- "Tracheal" (adjective): Pertaining to the trachea.
- The doctor suspected a tracheal infection.
- Insects have a tracheal system for respiration.
- In medical terminology, inflammation of the trachea is called tracheitis.
Variants and Related Words

- Tracheal (adj): Relating to the trachea.
- Tracheotomy (n): A surgical incision into the trachea, often to create an airway.
- Tracheostomy (n): A surgically created opening in the trachea into which a tube is inserted.
- Intubate (v): To insert a tube into the trachea to maintain an open airway.

Notes on Different Meanings
The word "trachea" has two distinct meanings based on context: 1. In vertebrate anatomy (including humans): It refers specifically to the single, cartilaginous tube known as the windpipe. 2. In invertebrate zoology: It refers to the many small, branching tubes in the respiratory system of arthropods. In this context, it is almost always used in the plural form tracheae.
Noun
- one of the tubules forming the respiratory system of most insects and many arachnids
- membranous tube with cartilaginous rings that conveys inhaled air from the larynx to the bronchi
