Human urine as compared to human blood is normally `:-`

Options

A. Hypotonic
B. Hypertonic
C. Isotonic
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Components of Human Urine and Blood:**
- Human urine primarily consists of water, urea, salts, ions, creatinine, and traces of ammonia.
- Human blood consists of plasma (the liquid component) and various blood cells, including red blood cells (RBCs), white blood cells (WBCs), and platelets.

2. **Analyzing the Solute-Solvent Ratio:**
- In human urine, the concentration of solutes (urea, salts, etc.) is higher compared to the amount of solvent (water).
- In contrast, human blood has a different composition where the solute concentration is lower relative to the solvent.

3. **Defining Tonicity:**
- Tonicity refers to the concentration of solutes in a solution compared to another solution.
- Isotonic: Solute concentration is equal to solvent concentration.
- Hypertonic: Solute concentration is greater than solvent concentration.
- Hypotonic: Solute concentration is less than solvent concentration.

4. **Determining the Tonicity of Human Urine:**
- Since human urine has a higher concentration of solutes than blood, it is classified as hypertonic.
- Therefore, in normal conditions, human urine is hypertonic compared to human blood.

5. **Selecting the Correct Option:**
- Based on the analysis, the correct answer is that human urine is hypertonic compared to human blood.

**Final Answer:**
Human urine as compared to human blood is normally **hypertonic**.
