Effect of erythromycin on gastric emptying

摘要

Motility is a general term that embraces all movements of the gastrointestinal tract, such as contractions of smooth muscle, the intralumunal pressures , and the transit of chyme throughout the bowel. These movements are modified by the actions of specialized segments of the intestine and the sphincters; and the whole is integrated by neural and humoral levels of control. Motility is best understood teleologically, i.e. as a process that facilitates the other, more fundamental functions of the gut. The stomach has three major functions: 1. Accommodating meals of variable volumes; 2. Grinding solid food into small particles; 3. Facilitating the process of gastric emptying.
