Oxygen passes through the aveoli (small air sacs in your lungs), and binds to the hemoglobin molecule. Above a certain partial pressure of O2, it binds easily to Hemoglobin molecules.
When the blood gets to tissues, the partial pressure of the O2 drops as the tissues use up the oxygen, this causes the hemoglobin to release it's oxygen load.

Air has 21% oxygen and the oxygen is measured in a pressure that is called millimeters of mercury. That "pressure" is what causes the oxygen you breath in with each breath to pass from the blood into the lungs. Oxygen is going in with each breath and carbon dioxide is going out. The oxygen pressure is lower when you go to a higher altitute (like Denver Colorado) and that's why athletes who don't live there get "short of breath" when they exert themselves. That is also why airplanes are "pressurized". Hope that helps.
