Under which condition can you hold your breath longer?
First breathe in as much as you can and hold your breath, and time it. (Lungs completely inflated)
After, breathe out as much as you can, hold your breath, and time it. (Maximal expiration).
Which condition can you hold your breath longer? Why?
It has been pointed out that maximal inhalation contains enough oxygen to supply the body for a long time. However, it is also noted that after maximal exhalation, there is decreased carbon dioxide in the blood.
That's why I'm confused, thanks!
The proportion of CO2 in the blood determines the hypothalamic response to encourage breathing. I believe the inhaling of air would reduce the CO2 concentration more than exhaling, thus allowing you to hold your breath longer.
I hope this helps. However, this is not my major area of expertise.
i got it!
thats close but not right :)
