The respiratory system is the first link in the process of oxygen delivery to the body's tissues. The transport of oxygen in the air you breathe to the alveoli in your lungs allows for the diffusion of oxygen into the blood stream.
The respiratory system uses the diffusion of oxygen and carbon dioxide. You inhale the oxygen which goes through the alveoli and thew capillaries in the lungs and you exhale it through the same section you inhale from. Therefore they diffuse together.

When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
Capillary walls receive oxygen in the lungs by a process known as diffusion.
