Question:
pH of Jejunum
pH of Jejunum
Show Hint
Remember, the pH gradually increases from acidic in the stomach (around 1–3) to neutral or slightly alkaline in the small intestine (around 6–7.5), which helps enzymatic digestion and absorption.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The jejunum is part of the small intestine where the pH is slightly alkaline to neutral, generally around 6.8 to 7.4. This mildly alkaline environment aids in the function of intestinal enzymes and nutrient absorption.
The options given show various pH values, but the value closest to the physiological pH of the jejunum is (a) 6.8±4, representing the expected pH range.
