What is the order of cells in the digestive system?

The order of cells in the digestive system can be described in terms of the types of cells involved in digestion. It begins with specialized epithelial cells lining the oral cavity, stomach, and intestines, which secrete enzymes and mucus. Next, gastric and intestinal cells help in the breakdown of food, while absorptive epithelial cells in the intestines facilitate nutrient absorption. Finally, various types of cells in the pancreas and liver contribute to digestion and metabolism by producing digestive enzymes and bile.
