Hormone gastrin is secreted by

Options

A. Cardiac glands
B. Chiefcells ofoxyntic glands
C. G-Cells ofpyloric region
D. Parietal cells ofoxyntic glands

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where the hormone gastrin is secreted from.

2. **Identifying the Options**: The options given are:
- A. Cardioglans
- B. Chief cells of gastroglans
- C. G-cells of pyloric region
- D. Parietal cells of gastroglans

3. **Recalling the Function of Gastrin**: Gastrin is a peptide hormone that plays a crucial role in the digestive process by stimulating the secretion of gastric acid.

4. **Locating the Source of Gastrin**: Gastrin is specifically produced by G-cells, which are located in the pyloric region of the stomach.

5. **Understanding the Role of G-cells**: G-cells release gastrin in response to food entering the stomach, which in turn stimulates parietal cells to secrete hydrochloric acid (HCl), aiding in digestion.

6. **Eliminating Incorrect Options**:
- A. Cardioglans: Not related to gastrin secretion.
- B. Chief cells of gastroglans: These cells produce pepsinogen, not gastrin.
- D. Parietal cells of gastroglans: These cells secrete HCl but do not produce gastrin.

7. **Concluding the Answer**: The correct answer is C. G-cells of pyloric region, as they are responsible for the secretion of the hormone gastrin.

**Final Answer**: C. G-cells of pyloric region
