Succus entericius is secreted by-

Options

A. Gastric glands
B. Islests of Langerhans
C. Crypts of lieberkuhn & Brunner's gland
D. Goblet cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the source of Succus Entericus, which is a digestive fluid found in the small intestine.

2. **Analyzing the Options**:
- **Option 1: Gastric Glands** - These glands are located in the stomach and secrete gastric juice, not Succus Entericus. Thus, this option is incorrect.
- **Option 2: Isles of Langerhans** - These are clusters of cells in the pancreas that produce insulin and glucagon, not involved in the secretion of Succus Entericus. Hence, this option is also incorrect.
- **Option 3: Crypts of Lieberkühn and Brunner's Glands** - Brunner's glands are located in the duodenum (the first part of the small intestine) and secrete alkaline mucus to neutralize stomach acid. The Crypts of Lieberkühn secrete intestinal juice, which aids in digestion. This combination is responsible for the secretion of Succus Entericus. Therefore, this option is correct.
- **Option 4: Goblet Cells** - These cells secrete mucus in the intestine but do not specifically secrete Succus Entericus. This option is incorrect.

3. **Conclusion**: The correct answer is that Succus Entericus is secreted by the Crypts of Lieberkühn and Brunner's Glands.

**Final Answer**: Succus Entericus is secreted by Crypts of Lieberkühn and Brunner's Glands.
