Question:
Absorption of Aspirin takes place in ________.
Absorption of Aspirin takes place in ________.
Show Hint
Aspirin is a weak acid that remains un-ionised in acidic gastric juice, so it can cross the gastric lining.
Updated On: Nov 12, 2026
- stomach
- mouth
- small intestine

Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
The stomach absorbs only a few substances: water, some simple sugars, alcohol and certain drugs.
Step 2: Nature of aspirin
Aspirin (acetylsalicylic acid) is a weak acid. In the acidic stomach it stays un-ionised and lipid-soluble, so it diffuses across the gastric mucosa.
Step 3: Conclusion
This is also why aspirin can irritate the stomach lining. Absorption therefore takes place in the stomach.
Final Answer:
Aspirin is absorbed in the stomach. \[ \boxed{\text{(A) }\text{stomach}} \]
