Document Summary
Concept 40. 1: animal form and function are correlated at all levels of organization. Physical laws, especially physics of exchanging materials with the environment, limits range of animal forms. 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. Large complex animals have highly folded or branched internal materials. The organization of the animal body involves a hierarchy of structures. The correct order of this hierarchy from least to most complex is ___. Covers the outside of the body and lines the organs and cavities within the body. Functions mainly to bind and support other tissues. Composed of sparsely packed cells scattered throughout an extracellular matrix. Major types: loose connective tissue, adipose tissue, fibrous connective tissue, cartilage, bone, blood. Composed of long cells called muscle fibers capable of contracting in response to nerve signals.
