What does the hanging part at the back of the throat do?
The hanging part at the back of the throat is called the palatine uvula or uvula. As it is usually found only in humans, scientists state that it primarily helps with speech. Additionally, it helps to guide the flow of food and water, by stopping them from going into the nose. It also produces saliva, making the throat well lubricated.
