In which of the following order, the process of digestion proceeds ?

Options

A. Digestion `rarr` Ingestion `rarr` Absorption `rarr` Assimilation `rarr` Egestion
B. Digestion `rarr` Ingestion `rarr` Assimilation `rarr` absortion `rarr` Egestion
C. Ingestion `rarr` Digestion `rarr` Assimilation `rarr` Absorption `rarr` Egestion
D. Ingestion `rarr` Digestion `rarr` Absorption `rarr` Assimilation `rarr` Egestion

Answer

To determine the correct order of the digestion process, we will break down the steps involved in digestion and analyze the options provided.

### Step-by-Step Solution:

1. **Ingestion**: The first step in the digestion process is the ingestion of food. This is when food is taken into the body through the mouth.

2. **Digestion**: After ingestion, the next step is digestion. This process begins in the mouth where food is mechanically broken down by chewing and mixed with saliva, and continues in the stomach and small intestine where enzymes further break down the food.

3. **Absorption**: Once the food is digested, the next step is absorption. This occurs primarily in the small intestine, where the digested nutrients are absorbed into the bloodstream.

4. **Assimilation**: After absorption, the body utilizes the absorbed nutrients for energy, growth, and repair. This process is known as assimilation.

5. **Egestion**: The final step in the digestion process is egestion, which is the elimination of undigested food and waste from the body.

### Correct Order:
The correct order of the digestion process is:
1. Ingestion
2. Digestion
3. Absorption
4. Assimilation
5. Egestion

### Conclusion:
Based on the breakdown of the digestion process, the correct answer is the option that lists the steps in the order: Ingestion → Digestion → Absorption → Assimilation → Egestion.
