If the face is covered then how does water get into the nose and mouth?

Imagine taking a ziploc sandwich bag, placing it in someone's mouth when they are on an upside down incline, and then running a strong stream of water into the bag.

It will feel like your mouth is filling up with water and when you are upside down the water will flow from the bag into your nostrils even though gravity will prevent the water in your nostrils from flowing up into your lungs.

Thanks. So water is going into the nose?
