Unformatted text preview: The ration of surface area to volume (SA:V) decreases with increasing size. See for yourself . Take a cube that is 1 inch on a side, what is the SA:V for this cube? Increase the cube to 2 inches on a side .what is the SA:V now? Finally consider a cube that is 4 inches on a side This relationship has implications for gas exchange, mobility, waste elimination, thermoregulation, and more. The myriad organ systems of most multi-cellular organisms are in part a response to this phenomenon. Another issue that has far reaching consequences in animal form and function is energetics. Different species have evolved very different strategies for accommodating their energetic needs. This is, in part, influenced by the SA:V relationship mentioned above...
