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.

Diffusion
One example of diffusion in the human body is the movement of oxygen from the lungs into the bloodstream. Oxygen molecules move from an area of high concentration (lungs) to an area of low concentration (bloodstream) through the respiratory membrane. This benefits the body by replenishing oxygen levels in the blood, which is essential for cellular respiration. Another example is the diffusion of glucose from the bloodstream into the cells. Glucose molecules move from an area of high concentration (bloodstream) to an area of low concentration (cells) through the cell membrane. This benefits the body by providing energy for cellular functions and metabolism.
Diffusion is the movement of a mineral or nutrient moving across the concentration gradient of a membrane. The closest word to diffusion would probobly be osmosis, which is the movement of water through a membrane.
The transfer of oxygen from the alveoli into the capillaries in the lungs, and the transfer of carbon dioxide from the capillaries into the alveoli (i.e. breathing in, and the oxygen going into the blood, and carbon dioxide going into the lungs to be expelled when we breathe out).
Diffusion is the movement of particles from a region of high concentration to a region of low concentration. An example would be putting a drop of food coloring in a glass of water. At first it will look dark and concentrated, after a while it will be spread out evenly.
Temperature affects the rate of diffusion, by speeding up the movement of molecules. For example it kind of like when going from water to steam. The water molecule get heat added and speed up, like that of diffusion.

The difference between Diffusion and Osmosis is by the process of them diffusing and the outcome such as an example of a sugar cube... In Diffusion Molecules move from high concentration just Osmosis although in the diffusion process of "Diffusion" it uses Kinetic energy and Concentration Gradient while "Osmosis" does not require cells to expand energy, in result Osmosis uses Passive Transport of Water.
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood.The alveoli have a very large surface area. In fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres. It is another example of the importance of the surface area: volume ratio.
This is diffusion. No energy required, molecules do this just based on random molecular motion. Example: a drop of ink dropped into a beaker of water will "diffuse" until it is as spread out as possible.
Diffusion, filtration, and osmosis. Diffusion.
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
