Question
Chapter 12.3, Problem 24CC
Summary Introduction
To determine: The change in the shape of the tube due to the contraction of the circular muscle layer of the intestine.
Introduction: The gastrointestinal tract consists of a series of multiple hollow organs. Thes organs include the mouth, esophagus, stomach, small and large intestine. The lining of these organs is made up of unstriated muscles.
Summary Introduction
To determine: The change in the shape of the tube due to the contraction of the longitundinal muscle layer of the intestine.
Introduction: the The inner lining of the gastrointestinal tract is made up of smooth muscles. These are non striated and involuntary muscles. These muscles contract and relax to support the movement of substances inside the hollow organs.
