Final answer:
The stomach produces hydrochloric acid (HCl) and intrinsic factor, both essential for the digestive process and the absorption of vitamin B12.The correct answer to which of the following products does the stomach produce is B.
Step-by-step explanation:
The stomach produces several substances that play important roles in digestion. Among the products the stomach produces are hydrochloric acid (HCl) and intrinsic factor. HCl is secreted by the parietal cells in the stomach and is necessary for the activation of pepsin from pepsinogen, which is secreted by the chief cells, as well as for maintaining the acidic environment necessary for digestion. Intrinsic factor is also secreted by the parietal cells and is crucial for the absorption of vitamin B12.
