Windpipe
From Memory Alpha, the free Star Trek reference
A windpipe, also known as a trachea, is a small tube inside a body that allows a person to breathe through the lungs.
In 2371, Neelix told Lieutenant Joseph Carey not to eat a Kaylo apple, given that they were poisonous. Neelix explained, in detail, that one of the symptoms of eating the apple was the windpipe began to swell up. (VOY: "State of Flux")
