Objective46,49: Relate Breathing to Cellular Respiration, Contrast Inspiration and Exhalation

This small video does a great job in explaining inspiration and exhalation. It is broken down into simple concepts. It also helped me to understand the pressure differences and how that effects breathing. Its actually pretty simple once I got the concept. I also found it helpful to review cellular respiration to further my understanding of how breathing takes place. There are a lot of things that have to happen to keep us breathing. A lot of things we have difficulty with as we age. Even things down to the muscles of inspiration can keep us from getting the oxygen we need to properly breath.
