No, blood is not 100% water.
While blood contains a significant amount of water, it also contains other important components. According to information available (16-Mar-2023), over 90% of blood plasma is water, but the remaining portion consists of dissolved substances, primarily proteins. Blood also contains electrolytes, vitamins, nutrients like glucose and amino acids, and blood cells (mainly red blood cells). Red blood cells make up over 99% of the solid particles in the blood.
Here's a breakdown of blood composition:
| Component | Percentage |
|---|---|
| Water (Plasma) | Over 90% |
| Proteins (Plasma) | Less than 10% |
| Electrolytes | Present |
| Vitamins | Present |
| Nutrients | Present |
| Red Blood Cells | Significant |
