Question

What is the approximate daily volume of pancreatic secretion?

• A. 1.5 L
• B. 2.5 L
• C. 5.0 L
• D. 10 L

Hint:

It is similar to daily salivary volume, around one and a half litres.

Answer 1

The Correct Option is A

Step 1: The exocrine pancreas secretes pancreatic juice, an alkaline fluid rich in bicarbonate and digestive enzymes, into the duodenum.

Step 2: The normal daily volume of pancreatic secretion is approximately 1.5 litres per day (commonly quoted as about 1.2 to 1.5 litres).

Step 3: For comparison, saliva is about 1.5 litres/day, gastric juice about 2 to 2.5 litres/day, and bile about 0.5 litres/day. The pancreatic value sits at roughly 1.5 litres.

Step 4: Therefore option a, 1.5 L, is the correct answer; the larger volumes given are far too high for pancreatic juice.
