breathing is when you can breath yourself without the help of anything however ventilation is when you need the help of something to breath.....
Pulmonary ventilation is the volume air that is breathed in or out in a single minute. It is the sum of the tidal volume (volume of air per breath) and the ventilation rate (the number of breaths per minute). For an individual's pulmonary ventilation to increase, there must be an increase in at least one of these two values. The individual can begin breathing deeper at the same rate (increasing tidal volume) or the individual can begin breathing faster at the same volume (increase ventilation rate) or both.
