During prolonges starvation, body derives nutrition from storage of -

Options

A. Liver and adipose tissue
B. Spleen
C. Liver and lungs
D. Subcutaneous fat and Pancreas

Answer

**Step-by-Step Solution:**

1. **Understanding Nutritional Sources**: During prolonged starvation, the body needs to derive energy from stored nutrients since food intake is absent. The primary sources of energy in the body are glucose, fats, and proteins.

2. **Initial Energy Source - Glycogen**: The body initially uses glycogen, which is a stored form of glucose. Glycogen is primarily stored in the liver and skeletal muscles. During the first few days of starvation (approximately 4-5 days), the body will utilize these glycogen stores to meet its energy requirements.

3. **Secondary Energy Source - Fat**: Once glycogen stores are depleted, the body shifts to using fat as its next source of energy. Fat is stored in adipose tissue throughout the body. This process allows the body to sustain energy levels for a longer duration during starvation.

4. **Tertiary Energy Source - Protein**: If starvation continues and fat stores are also exhausted, the body will begin to break down protein for energy. Proteins are found in muscles and other tissues, and their breakdown can lead to muscle wasting.

5. **Conclusion**: In the context of prolonged starvation, the body derives nutrition primarily from fat stores, specifically subcutaneous fat, after glycogen stores have been depleted.

**Final Answer**: During prolonged starvation, the body derives nutrition from the storage of **subcutaneous fat**.
