The correct Answer is:
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.** ---
