Detailed explanation-1: -“Facilitated diffusion is a type of diffusion in which the molecules move from the region of higher concentration to the region of lower concentration assisted by a carrier.”

Detailed explanation-2: -Simple Diffusion One example of passive transport is diffusion, when molecules move from an area of high concentration (large amount) to an area of low concentration (low amount). Molecules are said to naturally flow down their concentration gradient.

Detailed explanation-3: -Diffusion. During diffusion, substances move from an area of high concentration to an area of low concentration, until the concentration becomes equal throughout a space. Image showing the process of diffusion across the plasma membrane. Initially, the concentration of molecules is higher on the outside.

Detailed explanation-4: -Diffusion is an important process in human physiology. Specifically, diffusion is the mechanism of movement of oxygen, nutrients and other molecules across the capillary walls and the movement of other molecules across membranes.

Detailed explanation-5: -During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient.
