Human fluid connective tissue is devoid of

Options

A. prothrombin
B. calcium
C. reticular fibres
D. fibrinogen

Answer

To answer the question "Human fluid connective tissue is devoid of," we need to analyze the characteristics of human fluid connective tissue, specifically blood, which is the primary fluid connective tissue in humans.

### Step-by-Step Solution:

1. **Understanding Fluid Connective Tissue**:
- Human fluid connective tissue primarily refers to blood, which consists of a liquid matrix known as plasma.

2. **Identifying Components of Blood**:
- Blood contains various components including red blood cells, white blood cells, platelets, and plasma proteins.

3. **Analyzing the Options**:
- **Option 1: Prothrombin** - This is a protein involved in blood clotting. It is present in blood, so this option is incorrect.
- **Option 2: Calcium** - Calcium is a mineral that plays several roles in the body, including blood clotting. It is also present in blood, making this option incorrect.
- **Option 3: Reticular Fibers** - These fibers are a type of connective tissue fiber that forms a network to support soft tissues. However, they are not present in blood, which is why this option is correct.
- **Option 4: Fibrinogen** - This is a plasma protein that is crucial for blood clotting. It circulates in the blood, so this option is also incorrect.

4. **Conclusion**:
- The correct answer is **Option 3: Reticular Fibers**, as human fluid connective tissue (blood) is devoid of reticular fibers.

### Final Answer:
Human fluid connective tissue is devoid of **reticular fibers**.
