What is the definition of diffusion anatomy?

Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.

What is a diffusion in medical terms?

Medical Definition of diffusion 1 : the process whereby particles of liquids, gases, or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration.

What is meant by facilitated diffusion?

Facilitated diffusion is the transport of substances across a biological membrane from an area of higher concentration to an area of lower concentration with the help of a transport molecule. Since substances move along the direction of their concentration gradient, chemical energy is not directly required.

What is the best definition of diffusion?

diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

What are the types of diffusion in science?

Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion.

What is diffusion in nursing?

Definition: Passive transport of solutes across cell membranes from an area of higher concentration to one of lower concentration. This movement continues until equilibrium is reached on both sides of the membrane. Page 2. VCU School of Nursing.

What is facilitated diffusion and example?

The transport of glucose and amino acid from the bloodstream into the cell is an example of facilitated diffusion. Because glucose and amino acid are larger molecules, they require carrier proteins called glucose transporters or amino acid permeases, respectively for their transport from the bloodstream into the cell.

What is the definition of diffusion in chemistry?

Diffusion Definition. “Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”. Read on to explore what is diffusion and the different types of diffusion.

How are gasses and molecules in a liquid diffuse?

Gasses and molecules in a liquid have a tendency to diffuse from a more concentrated environment to a less concentrated environment. Passive transport is the diffusion of substances across a membrane.

Where does diffusion occur in the cell membrane?

Diffusion is the way of passive transport of substances in and out of the cell across the cell membrane. Diffusion occurs down the concentration gradient, i.e. from higher concentration to lower concentration.

Which is the best description of passive diffusion?

Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Passive diffusion is the movement of molecules across a membrane, such as a cell membrane. The movement does not require energy.
