Question

What protects the small intestines from the acidic chyme that is released from the stomach?

a. bicarbonate from the pancreas
b. Chyme is released in small amounts into the small intestines
c. Bicarbonate from the liver
d. a and b
e. b and c

Answer 1

The correct answer will be option-D.

Step-by-step explanation:

The HCl secreted from the stomach makes the food or chyme acidic which can harm the digestive organs like small intestine.

So to protect the small intestine from the acidic nature of the chyme, the chyme enters the duodenum through pyloric sphincter which controls the movement of chyme to intestine and allows the slow movement of chyme,.

The pancreatic juice released from the pancreas contains enzymes and bicarbonates which neutralizes the action of HCl and hence prevent the small intestine.

Thus, option-D is the correct answer.
