What happens when your trachea stops working?

Answer 1

I think you die. The trachea is like a tube connecting the mouth/oral airway to the lungs. The trachea will stop working if it becomes blocked eg by a foreign body - oh no I shouldn't inhale marbles!, or if it collapses in on itself. If the trachea is blocked there is no gas exchange with blood in the lungs. ie hypoxia (low oxygen and hypercapnoea ( high carbon dioxide levels) result which rapidly lead to cardiac dysfunction and death.
