Ch 40: basic principles of animal form and function4/29/2014 7:07:00 pm: animal form and function are correlated at all levels of organization. Physical laws, especially physics of exchanging materials with environment, limits range of animal forms: exchange in simple organisms (see fig. 40. 3: 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, exchange in complex animals (see fig 40. 4) 2: large, complex animals have highly folded or branched internal surfaces, this increases surface area, cell in these surfaces are specialized for exchanging materials. 4: connective tissue, functions mainly to bind and support other tissues. Composed of sparsely packed cells scattered throughout an extracellular matrix. Includes the layer beneath the skin called the loose connective tissue, Fibrous connective tissue, cartilage, bone, adipose, blood and. Lymph: the soft connective tisue has three types:
