What Does the Uvula Do?
6. Gag Reflex
The gag reflex, although not exactly pleasant, is another involuntary reflex that can be very beneficial for us. It can help to protect us against choking, which could potentially be fatal in some cases. Again, many people feel that the uvula is very useful in this regard.
If you were to place too much food at the back of the throat then the food will likely trigger the uvula. This, in turn, can trigger the gag reflex, preventing us from swallowing more food than we can handle. It also causes an unpleasant sensation that causes us to react to something too large being placed at the back of the throat.
