What does a Uvula do?

David's nose and throat have been pretty dried out from the oxygen. He keeps complaining about his uvula and asking what it does.
More ice keeps it cool and moist but he sure wishes he didn't have one right about now.
He got up and walked about 30 feet this morning then he brushed his teeth and got a sponge bath. He really did smile for the picture but I missed it.
Now we are waiting for the doctor to come in and see what happens next.
Cream of Wheat is for breakfast. Yum, Yum!
