Question

Given below are two statements:
Statement (I): The hormone secretin stimulates secretion of gastric juice in the stomach.
Statement (II): It also stimulates secretion of bile juice from the liver.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Gastrin controls gastric juice. Secretin acts on the pancreas and also affects the liver.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Secretin is released by the duodenal mucosa when acidic chyme enters the duodenum.

Step 2: Check Statement (I)
Gastric juice secretion is stimulated by gastrin, not by secretin. Secretin in fact tends to suppress gastric secretion. So Statement (I) is incorrect.

Step 3: Check Statement (II)
Secretin acts on the pancreas to release a watery juice rich in bicarbonate and also increases the secretion of bile from the liver. So Statement (II) is correct.

Step 4: Choose the option
Statement (I) is incorrect and Statement (II) is correct.

Final Answer:
Statement (I) is incorrect but Statement (II) is correct. \[ \boxed{\text{(D) }\text{Statement (I) is incorrect but Statement (II) is correct.}} \]
