Pancreatic juice rich in water & electrolytes, poor in enzymes are secreted by
**Core Concept**
The pancreas secretes two types of juices: one rich in enzymes and the other rich in bicarbonate and water. The **exocrine pancreas** is responsible for secreting digestive enzymes, while the **pancreatic ductal cells** secrete a juice rich in **bicarbonate** and water.
**Why the Correct Answer is Right**
The correct answer is related to the type of pancreatic secretion that is rich in water and electrolytes, such as **bicarbonate**, and poor in enzymes. This type of secretion is crucial for neutralizing the acidic chyme entering the duodenum from the stomach. The **ductal cells** of the pancreas are responsible for this type of secretion.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the type of pancreatic secretion.
**Option B:** This option is incorrect because it does not specify the type of pancreatic secretion.
**Option C:** This option is incorrect because it does not specify the type of pancreatic secretion.
**Clinical Pearl / High-Yield Fact**
The pancreatic juice rich in **bicarbonate** plays a critical role in maintaining the **pH balance** in the duodenum, allowing for optimal enzymatic activity.
**Correct Answer:** D. Pancreatic ductal cells
