For our bodies and those of most other animals, the surface area-to-volume ratio is maintained by increasing the number of cells and not the size of each cell. What features of even the largest of animal bodies allow the cells access to oxygen, nutrients, and other resources? (choose all that apply; more than one answer may be correct) Specialized structures that have evolved within the organism provide synthetic substitutes to eliminate the need to exchange with the environment. Specialized structures that may be extensively branched or folded enable exchange with the environment. In organisms with body plans that are more complex than hydra or tapeworm, harmless blood-borne microorganisms provide exchange surfaces for nutrient and gas transfer to body cells. Internal body fluids, such as interstitial fluid, link surfaces for nutrient and gas exchange to body cells. Cells in areas of importance in the body are increased in size where nutrient exchange with the environment is vital.
