It keeps the combustion gases in the combustion chamber while keeping the coolant in the water jacket. A blown head gasket will allow coolant to leak into the combustion chamber, or externally, or could allow combustion gases into the cooling passages. If coolant leaks into the combustion chamber it will come out of your tail pipe as white smoke.
What to do if coolant comes out of cylinder block?
