Do you need your uvula

Answer 1

No, however it does play a role in swallowing. The nasal and oral cavity share a common point in your windpipe: the pharynx. This is why you can breathe through your mouth and your nose. When swallowing is initiated, the uvula moves upwards to block off the nasal passage to prevent food/liquid from entering it, which is why it's impossible to breathe at the same time.
