Give four histological differences between the stomach and the intestine?
The stomach is characterized by a thicker mucosal layer with gastric pits and glands that secrete acid and enzymes, while the intestine has a thinner mucosa with villi and microvilli for increased surface area and absorption. The stomach contains parietal cells and chief cells, whereas the intestine has absorptive enterocytes and goblet cells for mucus secretion. Additionally, the stomach has a distinct muscularis layer with three muscle layers (oblique, circular, and longitudinal), while the intestine has two muscle layers (circular and longitudinal). Lastly, the presence of Peyer's patches in the ileum of the intestine is another distinguishing feature absent in the stomach.
