(lovelove*_* by my side and away my points!!) heya lovely braniacs...a question to you all :)
when we eat by mouth,our wind pipe closes and food pipe opens so when we inhale air through mouth,does not the air react with the HCl released in our stomach?
Answers
Because in the Time of inhaling air windpipe opens and food pipe closes and wind pipe is connected to lungs so Air goes direct in lungs and in inhaling food the food pipe opens and wind pipe closes.
if you breathe through mouth then it doesn't effect you because if we inhale through mouth then the food pipe closes and wind pipe trachea opens.
it is suggested that the person should breathe by her nose because there is many dust particles in air that are trapped in nose but if we inhale through mouth then the dust particles present in air goes in our body and make us unhealthy.
So, try to breathe through your nose.
As u know, only one opens at a time..
Either your windpipe or your food pipe...
These two can open simultaneously only if you talk while eating...
Moreover HCl is in acid form...and also there is a long food pipe btw the mouth and the stomach..
So anyway, whether u breath through ur mouth or nose, HCl won't get mixed up with the air you breath.
But... it's always better to breath with ur nose... cause, the hair in nose traps many dirt particles in air with the help of sticky mucus...
So...air that u breath through ur nose is 'Comparitively' less polluted than you breath through your nose....
