The processes of distention and recoil have an essential role in the functions of arteries and lungs. In both organ systems, these processes involve to a great extent the connective tissues, in particular the manner in which the extracellular materials are arranged to afford such movements. This book concerns the microenvironment of the connective tissues in the walls of arteries and the stroma of lungs. Proteoglycans, collagen, and elastic fibers and their interrelationships are discussed by eight scientists who are established researchers in this area. Their reports include important...
