Definition

1. Noun:
   • Trachea (in zoology): A rigid, air-conducting tube in the respiratory system of insects and some other arthropods. It is part of a network of tubes that delivers oxygen directly to tissues.
   • Air tube / Windpipe (general): Can refer to any tube-like structure that carries air, though this is a more general and less common usage.

Usage Examples

• Noun:
  • Côn trùng hô hấp qua hệ thống ống khí. (Insects breathe through a system of tracheae.)
  • Ống khí của sâu bướm rất nhỏ. (The caterpillar's trachea is very small.)

Advanced Usage

• In scientific contexts, "ống khí" is the standard term for the respiratory tubes in arthropods. The related branch of zoology is "phân ngành ống khí" (Tracheata), a subphylum comprising arthropods that breathe via such tubes, like insects, myriapods, and some arachnids.

Variants and Related Words

• Khí quản (n): This is the specific and common term for the or in vertebrate animals, including humans.
  • Dị vật mắc trong khí quản rất nguy hiểm. (A foreign object lodged in the trachea is very dangerous.)

Synonyms

• Trachea (primary biological synonym).
• Windpipe (for the general concept of an air tube, though "khí quản" is more precise for vertebrates).

Notes

• "Ống khí" is a specialized term primarily used in zoology and biology. In everyday language, to refer to the human windpipe, the word "khí quản" is always used instead.
