If diffusion did not occur, the body would be unable to move a lot of its materials … This lesson will provide you with a definition of simple diffusion. ... or advice of a legal, medical, or any other professional. The material that diffuses could be a solid, liquid or gas. In biology, both terms pertains to a type of passive transport. Everett Rogers, a professor of communication studies, popularized the theory in his book Diffusion of Innovations; the book was first published in 1962, and is now in its fifth edition (2003). Diffusion Definition. Diffusion is widely used in various fields such as biology, physics, chemistry, etc. It occurs in gases, liquids, and solids. Diffusion is driven by a gradient in concentration. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. The model presents a rationale of how current adopters and potential adopters of a new product interact. Medical Definition of Perfusion Medical Author: William C.

This is an important part of lung testing, because the major function of the lungs is to allow oxygen to "diffuse" or pass into the blood from the lungs, and to allow carbon dioxide to "diffuse" from the blood into the lungs. Diffusion, facilitated diffusion and osmosis are the types of passive transport: Allows molecules to pass the cell membrane, disrupting the equilibrium established by the diffusion: A dynamic equilibrium of water, nutrients, gasses, and wastes are maintained between cytosol and extracellular environment Diffusion definition, act of diffusing; state of being diffused. 2. ; A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored.
