Can you completely control your breathing rate by deciding to breathe more slowly? Why or why not?
While you can consciously control your breathing rate to some extent—such as by deciding to breathe more slowly or holding your breath—breathing is primarily an automatic process regulated by the autonomic nervous system. The medulla oblongata in the brainstem detects levels of carbon dioxide and oxygen in the blood and automatically adjusts the breathing rate to maintain homeostasis.
If you attempt to breathe very slowly or hold your breath for too long, the rising levels of carbon dioxide in your blood will eventually trigger an involuntary urge to breathe, overriding your conscious control. Thus, while you have some influence over your breathing rate, it is ultimately not completely under your conscious control.
in one sentence
You can partially control your breathing rate consciously, but it is primarily regulated automatically by the brain in response to carbon dioxide and oxygen levels, making it impossible to completely override this system for an extended period.
