What Does Your Uvula Do?

The video explains the uvula, a small fleshy structure at the back of the throat, and its roles in swallowing, saliva production, speech, and snoring. It highlights that humans are the only mammals with a uvula, which helps prevent food from entering the nasal passage. The uvula's glands produce saliva, aiding in lubrication during speech and eating. It also plays a role in immune defense. Enlarged uvulas can cause snoring and sleep apnea. While not vital, the uvula can be removed if problematic, though it may lead to a dry mouth. Its evolutionary purpose remains unclear.
