The statement 'The primary function of the stomach is not absorption because of limited blood supply' is true or false?

• A. False
• B. True
• C. Depends on drug
• D. Not enough information

Answer: (A)

Absorption in the stomach is not the main job of that organ; its primary role is digestion and mixing of food with acid and enzymes. While some substances can be absorbed there, the extent is limited and depends more on surface area, residence time, and the drug’s properties (such as pH-dependent ionization) than on blood supply alone. The stomach has relatively small surface area compared with the small intestine, and contents move into the intestine relatively quickly, which limits how much can be absorbed. Blood flow to the stomach is sufficient for its functions and isn’t the controlling reason for limited absorption. Some drugs (like very lipophilic ones or certain weak acids in acidic pH) can be absorbed to a small degree, but overall the stomach is not a major site of absorption. Therefore the statement is false.
