The trachea is the tube leading to the lungs. There has to be an opening to the lungs for breathing to occur. It our lungs were not attached to the mouth via the trachea, then the lungs would need an opening elsewhere. Besides, the trachea is for speaking as well, and you exhale across your vocal folds as you speak.
