Document Summary
Chapter 40: basic principles of animal form and function. Concept 40. 1: animal form and function are correlated at all levels of organization. Physical laws, especially physics of exchanging materials with environment, limits, rand of animal forms. Exchange in simple organisms: single-celled organisms, exchange material by diffusion, entire plasma membrane is exposed to medium, multicellular organisms with a sac body plan, body wall is only 2 cell-layers thick, exchange is by diffusion. Figure 40. 3: large, complex animals have highly folded or branched internal surfaces specialized for. Exchange in complex animals exchanging materials: this increases surface area. Clicker question: the organization of the animal body involves a hierarchy of structures. The correct order of this hierarchy from least to most complex is ____________. Epithelial tissue: covers the outside of the body and lines the organs and cavities within the body, cells are closely joined.
