How Does Histology Help in Understanding the Digestive System?
The digestive system includes various organs such as the esophagus, stomach, and intestines. Histology allows us to examine the layers of these organs, such as the mucosa, submucosa, muscularis externa, and serosa. For example, the stomach has specialized cells like parietal cells that secrete hydrochloric acid, and histological studies help us understand how these cells function and contribute to digestion.
