Why do we have to contract our throat when swallowing water? I mean it could just slide right down to our tummies.

not sure I’m right..
there are 2 tubes in throat: for air and for food.
usually the tube for air is open and the tube for food is closed.
when we eat/drink something, we need to open the tube for food and close the tube for air.
Also that is why you shouldn’t talk while eating (talking opens the air tube and food can get into it)
