Sweating is meant for

Options

A. Killing of skin bacteria
B. Regulation of body temperature
C. Removal of excess salt
D. Removal of excess water

Answer

**Step-by-Step Solution:**

1. **Understanding Sweating**: Sweating, also known as perspiration, is the process through which the body releases fluid from sweat glands located beneath the skin.

2. **Function of Sweating**: The primary function of sweating is to regulate body temperature. When the body temperature rises (for example, during exercise or in hot weather), the sweat glands produce sweat.

3. **Mechanism of Cooling**: As sweat evaporates from the skin surface, it cools the body down. This is a crucial mechanism for maintaining homeostasis and preventing overheating.

4. **Evaluating the Options**:
- **Option A**: Killing of skin bacteria - This is not the primary function of sweating.
- **Option B**: Regulation of body temperature - This aligns with the understanding of sweating as a cooling mechanism.
- **Option C**: Removal of excess salt - While sweat does contain salt, this is not its main purpose.
- **Option D**: Removal of excess water - This is not accurate as the body needs to retain water for various functions.

5. **Conclusion**: Based on the evaluation, the correct answer is **Option B: Regulation of body temperature**.
