Biomechanical Theory

Pp. 33-78 (46)

Abstract

This chapter aims to give the reader a basic understanding of mechanical theory, especially related to stresses and strains and how these parameters should be interpreted in comparison with more commonly used distensibility measures. The bioengineering way of thinking is introduced and references are made to functional aspects of the gastrointestinal tract. In order to understand the biomechanical complexity it is important to know about the complex anatomical features of the gastrointestinal tract as outlined in chapter 1 of this book.
