Pancreatic juice contain bicarbonate which is secreted by `:`

Options

A. paneth cells
B. goblet cell
C. kupffer's cell
D. Aciner cells

Answer

To answer the question "Pancreatic juice contains bicarbonate which is secreted by:", we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Components of Pancreatic Juice**:
- Pancreatic juice is a digestive fluid produced by the pancreas. It contains various components, including enzymes, water, salts, and bicarbonate ions.

2. **Identifying the Function of Bicarbonate**:
- Bicarbonate in pancreatic juice serves to neutralize stomach acid as it enters the small intestine, providing an alkaline environment for the enzymes to function effectively.

3. **Identifying the Cells Responsible for Secretion**:
- The pancreas consists of two main types of cells: endocrine cells (which secrete hormones like insulin) and exocrine cells (which secrete digestive enzymes and bicarbonate).

4. **Focusing on Exocrine Cells**:
- The exocrine portion of the pancreas is primarily composed of acinar cells. These cells are responsible for producing and secreting pancreatic juice, including bicarbonate.

5. **Evaluating the Options**:
- **Option A: Spinach cells** - Not correct, as they are not related to the pancreas.
- **Option B: Goblet cells** - Not correct, as they produce mucus, not bicarbonate.
- **Option C: Kupffer cells** - Not correct, as they are liver cells involved in phagocytosis.
- **Option D: Acinar cells** - Correct, as these cells are responsible for secreting pancreatic juice, including bicarbonate.

6. **Conclusion**:
- The correct answer is **Acinar cells**, which are responsible for the secretion of bicarbonate in pancreatic juice.

### Final Answer:
**Acinar cells**
