Find the mismatch

Options

A. Gastrin is a secretion ofG cells
B. GIP Inhibits gastric mobilty
C. CCK constrict gall bladder
D. Villikinin is a secretion of succusentericus

Answer

To find the mismatch among the given options related to digestion and absorption, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Option 1: Gastrin is a secretion of G-cells found in the stomach.**
- Gastrin is indeed secreted by G-cells located in the gastric mucosa of the stomach. It stimulates gastric acid secretion and is correctly described here.
- **Conclusion:** This option is correct.

2. **Option 2: GIP inhibits gastric motility.**
- GIP stands for Gastric Inhibitory Polypeptide, which does inhibit gastric motility and secretion. It is released in response to the presence of fats and glucose in the small intestine.
- **Conclusion:** This option is also correct.

3. **Option 3: CCK constricts the gallbladder.**
- CCK stands for Cholecystokinin, which is a hormone that stimulates the gallbladder to contract and release bile into the small intestine. Therefore, the statement that CCK constricts the gallbladder is misleading; it actually causes the gallbladder to contract.
- **Conclusion:** This option is incorrect.

4. **Option 4: Willykinin is a secretion of succus entericus.**
- Willykinin is not a secretion of succus entericus. Succus entericus refers to the intestinal juice secreted by the intestinal glands, which contains various enzymes. Willykinin is a hormone that increases the motility of the villi in the small intestine but is not part of succus entericus.
- **Conclusion:** This option is also incorrect.

### Final Mismatch Identification:
- The mismatched options are **Option 3** (CCK constricts gallbladder) and **Option 4** (Willykinin is a secretion of succus entericus). However, since the question asks for a single mismatch, **Option 4** is the most clearly incorrect statement.

### Answer:
**The mismatch is Option 4: Willykinin is a secretion of succus entericus.**
