Amount of water present inside human body cells is about

Options

A. 15 litres
B. 5 litres
C. 25 litres
D. 10 litres.

Answer

To determine the amount of water present inside human body cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Human Body Composition**:
- The human body is composed of various elements, with water being a significant component. Water is vital for various physiological processes.

2. **Water in Human Cells**:
- Water is found in different compartments in the body, including intracellular (inside cells) and extracellular (outside cells) fluids. The majority of the body's water is intracellular.

3. **Estimation of Total Body Water**:
- The average adult human body contains about 60% of its total weight as water. For example, in a 70 kg adult, this would be approximately 42 liters of water.

4. **Distribution of Water**:
- Out of the total body water, approximately two-thirds (or about 66%) is found inside the cells (intracellular fluid). This means that in a 70 kg person, about 28 liters of water would be inside the cells.

5. **Final Calculation**:
- While the total amount of water in cells can vary based on individual factors, it is commonly accepted that the amount of water present inside human body cells is around 25 liters. This is a general approximation for an average adult.

### Conclusion:
The amount of water present inside human body cells is approximately **25 liters**.
