THE ACT OF BREATHING.
How often do we respire? The number of our respirations per minute depends upon our age:
. Respirations per minute. One year 44 Five years 26 From 15 to 20 years ....** 20 From 20 to 25 years ...... 18£ From 25 to 30 years ...... 16 From 30 to 50 years ...... 18
Muscular exertion always increases the frequency of respiration. The higher the temperature the more frequent is the respiration. It has been shown that with higher atmospheric pressures than the normal the frequency of respiration is diminished, while the depth of each inspiration is increased. The frequency of respiration diminishes untH dinner-time, reaches its maximum within an hour of feeding, and thereafter falls again. If dinner is omitted no rise of frequency occurs.
