How does diffusion work?

In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space. For example, think about someone opening a bottle of cleaning ammonia in the middle of a room.

Can passive diffusion move things from low to high concentration?

However, you cannot use passive diffusion to move things from low concentration to high concentration but you can do this with facilitated/active. Depending on the difference in concentration, the simple/passive diffusion will vary while facilitated diffusion can move against concentration gradients and if affected by other conditions too.

What is the diffusion of oxygen carbon dioxide and inert gas?

” The Diffusion of Oxygen, Carbon Dioxide, and Inert Gas in Flowing Blood”. Biophys J. 7 (6): 827–851. Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas.

What is the difference between diffusion and osmosis?

Osmosis is a kind of diffusion. Diffusion is the movement of substances from a high to low concentration, while osmosis is the diffusion of water across a cell membrane that moves from high to low water potential (or, low solute concentration to high solute concentration).
