2. As a review activity, label figures 49.6 and 49 7.
3. Observe the torso, and locate the following features of the stomach:
rugae cardiac region fundic region body region pyloric region pyloric canal pyloric sphincter (valve) lesser curvature greater curvature
4. Examine a microscopic section of stomach wall, using low-power magnification. Note how the inner lining of simple columnar epithelium dips inward to form gastric pits. The gastric glands are tubular structures that open into the gastric pits. Near the deep ends of these glands, you should be able to locate some intensely stained (bluish) chief cells
and some lightly stained (pinkish) parietal cells (fig. 49.8). What are the functions of these cells?
5. Complete Part C of the laboratory report.
