How is the intestinal mucosa protected from the acidic food entering from the stomach?
Ans:
The activities of the gastrointestinal tract, are regulated by the neural system as well as the hormonal system. Many intrinsic and extrinsic nerves connect this tract. These nerves help in the coordinated functioning of several parts of the alimentary canal. Moreover, there are some hormones as well that play an important role in the coordination of these functions.
