Respiratory system
Looks like
Two pearly-white bands of muscle and lining stretched across the voice box, longer in males.
What it does
Vibrate to make the voice and close to protect the airway.
Keeping it well
Voice rest, hydration and not smoking; hoarseness lasting more than three weeks, especially in smokers, needs throat examination.
