Digestion process in humans is

Options

A. Extracellular
B. Intracellular
C. Intercellular
D. Both (a) and (c )

Explanation

### Step-by-Step Solution:

1. **Understanding Digestion**: Digestion is the process by which food is broken down into smaller components that can be absorbed by the body.

2. **Type of Digestion in Humans**: In humans, the digestion process is classified as **extracellular digestion**. This means that the breakdown of food occurs outside the cells, primarily in the digestive tract.

3. **Key Organs Involved**: The main organs involved in the digestion process in humans are:
- **Stomach**: Here, food is mixed with gastric juices, which contain enzymes and acids that begin the digestion of proteins.
- **Small Intestine**: This is where most of the digestion and absorption of nutrients occurs. Enzymes from the pancreas and bile from the liver aid in this process.

4. **Role of Enzymes**: Enzymes play a crucial role in digestion. They are biological catalysts that speed up the breakdown of food substances into simpler forms that can be absorbed by the cells.

5. **Absorption**: After digestion, the nutrients are absorbed through the walls of the small intestine into the bloodstream, where they are transported to various cells in the body.

6. **Conclusion**: Therefore, the correct answer to the question about the type of digestion process in humans is **extracellular digestion**.
