The process of digestion is accomplished by `:-`

Options

A. Mechanical process
B. Chemical process
C. Electric process
D. Both 1 & 2

Answer

**Step-by-Step Solution:**

1. **Understanding Digestion:**
- Digestion is the process by which food is broken down into smaller, absorbable components. This involves both mechanical and chemical processes.

2. **Mechanical Digestion:**
- Mechanical digestion refers to the physical breakdown of food.
- Example: When food enters the mouth, the teeth chew and grind it, which is a mechanical action.
- Another example is peristalsis, which is the wavy movement of food through the esophagus and intestines, aiding in the movement and mixing of food.

3. **Chemical Digestion:**
- Chemical digestion involves the breakdown of food through chemical reactions, primarily using enzymes.
- Example: Saliva in the mouth contains enzymes that begin the digestion of carbohydrates.
- In the stomach, gastric juices (which contain hydrochloric acid and enzymes) further break down food.
- The liver produces bile, and the pancreas secretes pancreatic juices, both of which contain enzymes that aid in the digestion of fats and proteins.

4. **Evaluating the Options:**
- Option A (Mechanical process): Correct, as mechanical digestion occurs through chewing and peristalsis.
- Option B (Chemical process): Correct, as chemical digestion occurs through various enzymes and digestive juices.
- Option C (Electric process): Incorrect, as there are no electrical processes involved in digestion.
- Option D (Both 1 and 2): Correct, as digestion involves both mechanical and chemical processes.

5. **Conclusion:**
- The process of digestion is accomplished by both mechanical and chemical processes. Therefore, the correct answer is option D (both 1 and 2).
