The food mixed thoroughly with the acidic gastric juice of the stomach by the churning movements of its muscular wall. What do we call the food then?

Options

A. Bolus
B. Chyme
C. Succus entericus
D. Chylomicron

Explanation

To answer the question, we need to understand the process of digestion in the stomach. Here’s a step-by-step breakdown:

1. **Food Ingestion**: The process of digestion begins when food is ingested and enters the stomach.

2. **Mixing with Gastric Juice**: In the stomach, the food is mixed with gastric juice, which is acidic in nature. This gastric juice contains hydrochloric acid and digestive enzymes that help break down food.

3. **Churning Movements**: The muscular walls of the stomach perform churning movements. These movements mix the food thoroughly with the gastric juice, ensuring that the food is broken down into smaller particles.

4. **Formation of Chyme**: As a result of this mixing and churning, the food transforms into a semi-liquid substance. This semi-liquid mixture is called "chyme."

5. **Conclusion**: Therefore, when food is mixed thoroughly with the acidic gastric juice of the stomach through churning movements, it is referred to as chyme.

**Final Answer**: The food mixed thoroughly with the acidic gastric juice of the stomach by the churning movements of its muscular wall is called chyme.
