Waste products such as carbon dioxide or urea travel by diffusion from body cells into the bloodstream. b] in fish gills [O2] c] facilitated diffusion of digested food into villi (tho most absorption occurs by active transport). Similarly in animals the transport of respiratory gases also occur by diffusion. d] diffusion of oxygen/nutrients etc into protozoa across cell membrane, and CO2, urea, other waste out. Diffusion is an important process in animals and plants. 0.007 µm), but in plant cells, this might vary. The diffusing molecules may be solids, liquids or gases. This disease is also referred to as leukoaraiosis. Myelin gives the white matter its color. Examples of diffusion in living organisms Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. Have you done some reading (e.g. Where does diffusion happen in the digestive system? Diffusion and osmosis occur when air or water molecules move from an area of high concentration to low concentration.
