Questions
Opinions
Respiration is one of many amazing things that the bopdy does for you for free and you don't have to even work for it but really you because its your body. I find this unit kind of interesting but it is difficult to understand if you don't pay attention. The one thing i don't get is how your body can move the diaphram to create a sort of vaccum to carry air in and out of the body. I always thought you sucked air in on your own will.
Additional
I went on google.com and found so really interesting facts on respiration but i wont give them all to you because that would make people stop asking questions.
- Central to the human respiratory system, they breathe in between 2,100 and 2,400 gallons (8,000 and 9,000 liters) of air each day—the amount needed to oxygenate the 2,400 gallons (9,000 liters) or so of blood that is pumped through the heart daily.
