Options

A. Consists of a fluid matrix (Plasma)
B. Has formed elements
C. Is the most commonly used body fluid by most of the higher organisms
D. All

Answer

### Step-by-Step Text Solution:

1. **Understanding Blood as a Connective Tissue**:
- Blood is classified as a special type of connective tissue. Unlike other connective tissues, it has unique characteristics that distinguish it from others like bone and cartilage.

2. **Fluid Matrix**:
- The matrix of blood is fluid in nature. This is an important feature because, unlike many other connective tissues that have a fibrous matrix, blood lacks these fibers. The absence of fibers allows blood to remain in a liquid state, which is essential for its function in the body.

3. **Formed Elements**:
- Blood contains formed elements, which are the cellular components of blood. These include:
- Red Blood Cells (RBCs): Responsible for transporting oxygen.
- White Blood Cells (WBCs): Part of the immune system, helping to fight infections.
- Platelets: Involved in blood clotting.
- These formed elements are suspended in the fluid matrix of blood.

4. **Common Body Fluid**:
- Blood is the most commonly used body fluid in higher organisms. It plays a crucial role in the circulatory system, facilitating the transport of nutrients, gases, and waste products throughout the body.

5. **Conclusion**:
- Therefore, all the statements regarding blood being a special type of connective tissue, having a fluid matrix, containing formed elements, and being a commonly used body fluid in higher organisms are correct.
