WebSolutes move by diffusion from regions of high concentration to regions of low concentration. Fick’s First Law of Diffusion states that the flux is proportional to the negative of the gradient of C: where Js is the solute flux, D is the diffusion coefficient, and ∂C /∂ x is the one-dimensional gradient. WebThe simplest form of movement is diffusion, in which solutes move from an area of high concentration to an area of low concentration; diffusion is directly related to molecular kinetic energy. Diffusion does not require energy input.

WebOsmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Semi-permeable membranes are very thin layers of material which allow some things to pass through them, but prevent other things from passing through. WebIt takes place by diffusion of gases through the general body surface of the skin. Gaseous exchange, that is, the intake of O 2 and giving out CO 2, takes place between the blood capillaries of the outer epidermis and the surface film of moisture contributed by the secreted mucus, excreted wastes, and coelomic fluid.
