Does respiration take place when you are sleeping?

Answer 1

Of course respiration takes place when you are sleeping! You have to breath to live. So unless you are a zombie then yes respiration occurs when you are sleeping as well as when you are awake.

Answer 2

There is no mechanism to filter carbon dioxide in humans. You will breathe carbon dioxide both when you are awake and also when you are sleeping.

Answer 3

Yes, respiration continues while you are sleeping. Your body still needs to take in oxygen and release carbon dioxide, so your respiratory system functions even when you are asleep.
