Answer:
The correct answer is B. The mucosa is responsible for absorption and secretion.
Explanation:
The mucosa is the deepest layer of the intestinal tract, surrounding the lumen, or space inside the tube. This layer comes into direct contact with food (or bolus) and is responsible for absorption and secretion, which are important processes in digestion.
The mucosa is highly specialized in each organ of the intestinal tract, facing a low pH in the stomach, absorbing a multitude of different substances in the small intestine and also absorbing specific amounts of water in the large intestine.
