Review of Anatomy of the Gastrointestinal System

There are several supplementary sources you can use to review anatomy and physiology information that is important to know to understand how gastrointestinal (GI) medications work. Figure 7.1^[1] illustrates the anatomical components of the GI system. Information is provided below to the OpenStax Anatomy and Physiology book for further details regarding the following selected areas: overview of the digestive system, digestive system processes and regulation, the stomach, the small and large intestines, and chemical digestion and absorption. In addition, supplementary videos found below further explaining the GI system and digestive system. Medications related to hyperacidity, bowel disorders, and nausea and vomiting will be discussed in this chapter with reference to how they target pathophysiological concepts related to these organs and processes.
