Blood is

Options

A. Acidic
B. Alkaline
C. Neutral
D. Variable .

Answer

**Step-by-Step Solution:**

1. **Understanding Blood pH**: Blood has a specific pH range that is crucial for its function. The normal pH of blood typically ranges from 7.35 to 7.45.

2. **Identifying the Nature of Blood**: To determine whether blood is acidic, alkaline, or neutral, we need to analyze its pH value. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.

3. **Analyzing the pH Range**: Since the pH of blood (7.35 to 7.45) is above 7, it indicates that blood is slightly alkaline.

4. **Role of Buffers**: The presence of carbonic acid and bicarbonate in the blood helps maintain this pH range, preventing it from becoming too acidic or too alkaline.

5. **Conclusion**: Based on the pH range and the buffering system in blood, we can conclude that blood is alkaline in nature.

**Final Answer**: Blood is alkaline.
