Document Summary
Graph body mass vs percent of body mass. Surface are relaive to size of organism is declining relaive to the size as the animal gets bigger (exponenial) profound efect of surface rule on animals of diferent size. Paricular science based on a simple linear equaion. Isometric changing proporionally to body size (brain size is 10% body weight, then brain size in elephant would be 10% of body weight) If you look at anatomy, we see that it is paradoxical in that most organ system and issues on a scale (more or less isometrically) Diagram blood, almost 50% of body mass, remains relaively the same across many body masses. Relaive invariance in the proporion of body weight. How does this go with the fact that the metabolic rate is changing exponenially. As you get smaller, the metabolic rate is going up, but the blood is the same % of the body weight (no extra to carry oxygen)
