Physics and Chemistry
Diffusion is the movement of particles from an area of high concentration to an area of low concentration. Diffusion is not to be confused with osmosis, which is the movement of water through a semi-permeable membrane. However, osmosis is a special case of diffusion.
Lighting (as in Photography)
Diffusion means to scatter light. A similar effect can be achieved by placing a Gelatin silk plate over a camera or projection lens.
Generally, from the eyes of a 7th grader, diffusion is when molecules of which are concentrated in one area spread out like if you spray air-freshener in one side of a room and the scent spreads throughout the room that is diffusion.

Water diffuses from the kidney back into the blood stream.
Oxygen diffuses into cells. Carbon dioxide diffuses out.
The molecule that diffuses out of the pores of the leaf is called water vapor.
This process occurs in the capillaries of the lungs. Here, oxygen from inhaled air diffuses into red blood cells in exchange for carbon dioxide, which then diffuses out of the red blood cells and is exhaled from the body.
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Thermal radiation is when heat diffuses off hot surfaces
diffuses in and out of the cell
Air exchange
yes while oxygen then diffuses into the blood, and carbon dioxide diffuses out. it's a chain
As it circulates, the oxygen diffuses into the blood via the alveolar wall, this then transfer the oxygen to the red blood cells, as diffusion occurs at this point, oxygen diffuses from a high concentration to a low concentration, so the oxygen diffuses into the blood whereas the CO2 diffuses into the alveoli and then out of the mouth when we expire.
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
