Definition Of Diffusion In Anatomy

In facilitated diffusion a molecule is transported across a membrane with the help of a carrier protein.

Definition of diffusion in anatomy. Diffusion definition diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. Similarly the medium in which diffusion occurs could also be in one of the three physical states. For diffusion to occur there must be a concentration gradient. Diffusion is the net passive movement of molecules or particles from regions of higher to regions of lower concentration.

Diffusion physics the process in which there is movement of a substance from an area of high concentration of that substance to an area of lower concentration. Diffusion is the net movement of molecules along their concentration gradient. The material that diffuses could be a solid liquid or gas. Simple diffusion is the process by which solutes are moved along a concentration gradient in a solution or across a semipermeable membrane.

This means that the molecules move from a region of higher concentration to a region of lower concentration. Diffusion is the net movement of anything for example atom ions molecules from a region of higher concentration to a region of lower concentration. Passive diffusion is the movement of molecules across a membrane such as a cell membrane. The dissimilarity in the amounts of solutes particles or molecules between the two regions will cause them to move between the two regions.

Movement of substances from an area of high concentration to an area of low concentration occurs mainly in gases liquids and solutions rate of diffusion increases with increase in temperature or increase in the concentration of diffusion substance diffusion can also occur across a semipermeable membrane. The movement does not require energy. Diffusion is driven by a gradient in concentration. Water molecules move in to surround individual solute molecules which maximizes hydrogen bonding.
