Answer:
All gases, wether in a liquid medium or not, are always trying to achieve equilibrium in terms of their pressure. Oxygen at high pressure will move to an area where oxygen is at low pressure. The partial pressure of oxygen will always be lower inside the body because it’s constantly being used up, so when you breath in, the oxygen will go from the relatively high partial pressure of oxygen in the air to the lower partial pressure of oxygen in your body. If you’re getting this question directly out of a book I would say it’s a little poorly worded if they’re only looking for a one word answer since you need two different partial pressures for gases to move anywhere. To say low pressure or high pressure for the condition seems incorrect.
