Why does oxygen move from the alveoli to the blood?

im studying for a science test and this is surrounded by the study guide but it isnt in my report and im blanking

Answers:    The partial pressure of oxygen in the blood is smaller quantity than the partial pressure in the atmosphere (which is pretty close to that within your lungs when you breathe in). Therefore, there's a gradient, so oxygen moves along that angle into the blood.

Similarly carbon dioxide moves out of the blood into the lungs along its gradient.
