The Vietnamese word "khí quản" refers to the windpipe or trachea in English. It is a noun that describes a vital part of the respiratory system in humans and many animals.
The khí quản is a tube that connects the throat (or pharynx) to the lungs. Its primary function is to allow air to pass in and out of the lungs, playing a crucial role in breathing. When you inhale, air travels through the khí quản to reach the lungs, and when you exhale, air moves back out through the khí quản.
In more advanced contexts, "khí quản" can be used in discussions about medical conditions, such as tracheitis (inflammation of the windpipe) or tracheostomy (a surgical procedure to create an opening in the trachea).
In general, "khí quản" specifically refers to the windpipe or trachea, and it does not have different meanings outside this context.
