    In simple organisms such as unicellular and one or two layer organisms materials can be transferred among cells by simple processes of diffusion However in large organisms a system is needed for the distribution and collection of materials this is because diffusion does not occur fast enough to carry the large volumes of materials necessary through the greater distance required

    OXYGEN Oxygen is obtained by the blood through the process of external respiration in the lungs. Oxygen is then transported to the individual body cells where it is used in the metabolic oxidation. This provides energy for the production of ATP Adenosine Triphosphate which is necessary for carrying on the life processes of the body
