The trachea is the tube that carries air from your throat down towards your lungstrachea是把空氣從喉嚨往下帶到肺部的那條管子. In everyday English almost nobody says 'trachea'在日常英文裡幾乎沒有人說'trachea' — they say 'windpipe'大家會說'windpipe'.

'Trachea' is the doctor's word: you meet it in a hospital, in a biology class, in a textbook. Both words point at the same tube, so if you know 'windpipe' you already know what a trachea is; you are just learning the formal name for it.

'Trachea' is the doctor's word'trachea'是醫生用的字: you meet it in a hospital, in a biology class, in a textbook你會在醫院、生物課、教科書裡遇到它.

Two things worth knowing about the word itself. First, the plural is usually 'tracheae', though 'tracheas' is also written and doctors say both. Second, it is one of those words people stress differently — in British English usually truh-KEE-uh, in American English often TRAY-kee-uh — so do not be confused when you hear it two ways.

Two things worth knowing about the word itself關於這個字本身，有兩件事值得知道. First第一, the plural is usually 'tracheae'複數通常是'tracheae', though 'tracheas' is also written and doctors say both不過'tracheas'也有人寫，醫生兩種都會說. Second第二, it is one of those words people stress differently這是那種大家重音唸法不同的字之一 — in British English usually truh-KEE-uh英式英文通常唸truh-KEE-uh, in American English often TRAY-kee-uh美式英文常唸TRAY-kee-uh — so do not be confused when you hear it two ways所以聽到兩種唸法時不用覺得奇怪.
