The result is rapid, massive destruction of muscular and soft tissues, eventually resulting in tissue death or gangrene.

Muscular tissue flaps called vocal cords open to let air into the lungs, close to prevent food or drink from going the wrong way and move when air pushes past them to produce speech.

被称为声带的肌肉组织瓣张开，让空气进入肺部；闭合，防止食物或饮料误入肺部；当空气推过声带时，声带就会移动，从而发出声音。
