The main functions of the GI tract include the digestion of food, absorption of nutrients, and elimination of waste. Pathologic conditions affecting the GI system result from the impairment of these functions. Malignancies in the GI tract, specifically the colon, are common conditions that affect this system. The most common signs and symptoms associated with GI disease include the following: (1) chest and/or abdominal pain, (2) disturbances in food ingestion (possibly due to vomiting, nausea, difficulty or painful swallowing, or anorexia),1 (3) alterations in bowel movements (constipation or diarrhea), and (4) bleeding in the GI tract. The anatomy of the GI system is shown in Figure 6–1. Table 6–1 summarizes the selected GI pathologies discussed in this chapter. Table 6–2 identifies organs associated with abdominal quadrants.
