The digestive tract lining is primarily composed of epithelial cells that serve protective and absorptive functions. Mucus-secreting goblet cells within the lining help lubricate and protect the gut from mechanical and chemical damage. Additionally, various hormones and signaling molecules regulate the function and health of the lining, influencing digestion, absorption, and immune responses. Overall, a balance of these components is essential for maintaining a healthy digestive system.
