Question

which of the following would occur in an individual if they had their stomach removed?
multiple choice
difficulty absorbing vitamin b₁₂
inability to emulsify lipids
inability to chemically digest carbohydrates
decreased ph in the duodenum

Explanation:

• Difficulty absorbing vitamin B12: The stomach produces intrinsic factor, which is necessary for the absorption of vitamin B12 in the small intestine. Without a stomach, intrinsic factor production stops, leading to difficulty absorbing vitamin B12.
• Inability to emulsify lipids: Lipid emulsification is mainly done by bile from the liver and gallbladder, not the stomach.
• Inability to chemically digest carbohydrates: Carbohydrate digestion starts in the mouth with salivary amylase and continues in the small intestine. The stomach has little role in carbohydrate chemical digestion.
• Decreased pH in the duodenum: The stomach releases acidic chyme. Without a stomach, less acid would enter the duodenum, so pH would not decrease (it might even increase compared to normal with stomach - chyme release).

Answer:

Difficulty absorbing vitamin B12
