How many of the following glands release their secretions that don't have a zymogen in them ?
Fundic glands , parotid glands, pancreatic acini , Hepatic lobules , Intestinal glands,

Options

A. 1
B. 2
C. 4
D. 5

Answer

To solve the question of how many of the listed glands release secretions that do not contain a zymogen, we will analyze each gland mentioned in the question:

1. **Fundic Glands**:
- These glands are located in the stomach and primarily secrete hydrochloric acid (HCl). They do not secrete any enzymes or zymogens.
- **Conclusion**: No zymogen present.

2. **Parotid Glands**:
- These are one of the salivary glands that secrete saliva, which contains the enzyme salivary amylase. Salivary amylase is an enzyme that initiates the digestion of starch.
- **Conclusion**: Zymogen present.

3. **Pancreatic Acini**:
- The pancreas secretes pancreatic juice, which contains several digestive enzymes in their inactive forms (zymogens), such as trypsinogen and chymotrypsinogen. These zymogens are activated in the small intestine.
- **Conclusion**: Zymogen present.

4. **Hepatic Lobules**:
- The liver produces bile, which is essential for the emulsification of fats but does not contain enzymes. Therefore, it does not contain any zymogens.
- **Conclusion**: No zymogen present.

5. **Intestinal Glands**:
- These glands secrete intestinal juice (succus entericus), which contains various enzymes for digestion, including peptidases and maltase.
- **Conclusion**: Zymogen present.

Now, let's summarize the findings:
- **Glands without zymogens**: Fundic glands and hepatic lobules.
- **Glands with zymogens**: Parotid glands, pancreatic acini, and intestinal glands.

**Final Count**: There are **2 glands** (Fundic glands and Hepatic lobules) that release secretions without zymogens.
