Respiratory System by Wrenlie

The most interesting about this topic is it's a necessary thing for survival and how it functions. The respiratory system functions with oxygen and carbon dioxide. The most important organs in the respiratory system is the lungs. The lungs take in oxygen and filters it then exhales out carbon dioxide. There is also red blood cells that carries oxygen throughout the whole body and carry carbon dioxide back to the lungs where it may leave the body.

Without a respiratory system you can not survive, a infants normal breath rate is 40 times per minute and matures to different breath rates by age.  The average adults is 12 to 16 per minute and increases through certains situations such as exercise. And children and women breath faster than a man.  We also loose around have a liter of water through breathing, that is why you're able to fog up a window. And that your right lung actually bigger than your left lung.

Questions:

1.      Why is this necessary for survival?

2.      How do red blood cells carry oxygen and carbon dioxide?

3.      Does having one bigger lung serve a purpose?
