The two fluid connective tissues found in the human body are :

Options

A. mucous and matrix
B. blood and lymph
C. ground substance and hyaluronic acid
D. collagen and plasma

Answer

**Step-by-Step Solution:**

1. **Understanding Fluid Connective Tissues**:
- Fluid connective tissues are specialized types of connective tissues that are characterized by a fluid matrix. They play a crucial role in the transport of substances within the body.

2. **Origin of Fluid Connective Tissues**:
- These tissues are derived from the mesoderm layer of the embryo. The mesoderm is one of the three germ layers formed during embryonic development, the other two being ectoderm and endoderm.

3. **Identifying the Types of Fluid Connective Tissues**:
- The two primary types of fluid connective tissues in the human body are blood and lymph.
- Blood serves as a transport medium for oxygen, nutrients, hormones, and waste products.
- Lymph is involved in the immune response and also helps in the transport of lymphatic fluid.

4. **Evaluating the Options**:
- Option 1: Mucus and matrix - Not fluid connective tissues.
- Option 2: Blood and lymph - Correct answer.
- Option 3: Ground substance and Hyaluronic acid - Not fluid connective tissues.
- Option 4: Collagen and plasma - Collagen is a protein, not a fluid connective tissue.

5. **Conclusion**:
- Based on the above analysis, the two fluid connective tissues found in the human body are blood and lymph.

**Final Answer**: Blood and lymph.
