Glucose, Oxygen, Carbon Dioxide 3 of 9 What are the smallest blood vessels? Why are they important? Capillaries, situated close by to every cell to supply them with glucose and oxygen and take away carbon dioxide 4 of 9 What is the process called whereby glucose, oxygen and carbon dioxide move between the cells and capillaries? Diffusion 5 of 9 Define Diffusion The gradual movement of particles from places of high concentration to low concentration 6 of 9 When cells respire what do they use and what do they produce? Use oxygen and glucose and produce carbon dioxide 7 of 9 What affects the rate of diffusion? The difference in concentration 8 of 9 The faster the rate of diffusion the bigger... the difference in concentration 9 of 9
