Diffusion Gradient

The molecules are more densely packed on the left and so they tend to diffuse into the space on the right. This is diffusion gradient.

Diffusion involves molecules from a high concentration to a low concentration across a concentration gradient.

Diffusion is an essential process that is going on inside your body right now and keeping you alive.

Diffusion occurs in the organ systems that control your breathing, circulation, digestion and other life processes.
