The food that enters into intestine from stomatch is

Options

A. Alkaline chyle
B. Fundus
C. Acidic chyme
D. Bolus

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of food that enters the intestine from the stomach.

2. **Defining Chyme**: The food in the stomach is transformed into a substance called chyme. Chyme is a semi-fluid mass of partially digested food mixed with gastric juices, which include hydrochloric acid (HCl) and digestive enzymes.

3. **Nature of Chyme**: In the stomach, chyme is acidic due to the presence of hydrochloric acid. This acidity helps in the digestion of food.

4. **Movement to the Small Intestine**: When chyme moves from the stomach to the small intestine, it is still acidic.

5. **Role of Secretin**: Upon entering the small intestine, the acidic chyme stimulates the secretion of a hormone called secretin. This hormone signals the pancreas to release bicarbonate, which is alkaline.

6. **Neutralization of Chyme**: The bicarbonate released by the pancreas neutralizes the acidity of the chyme, converting it into alkaline chyme in the small intestine.

7. **Evaluating the Options**:
- **Alkaline Chyme**: This is incorrect as it refers to the chyme after it has been neutralized in the small intestine.
- **Fundus**: This is the upper part of the stomach and not relevant to the question.
- **Acidic Chyme**: This is the correct answer, as it describes the state of chyme when it exits the stomach.
- **Bolus**: This refers to the food mass formed in the mouth and is not relevant to the question about what enters the intestine.

8. **Conclusion**: The food that enters the intestine from the stomach is called **acidic chyme**.
