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 the Question**: The question asks for the two fluid connective tissues found in the human body. Connective tissues are a type of tissue that supports, binds together, and protects tissues and organs of the body.

2. **Identifying the Options**: We need to analyze the options provided to determine which ones are classified as fluid connective tissues. The options include:
- Mucus and Matrix
- Blood and Lymph
- Ground substance and Hyaluronic acid
- Collagen and Plasma

3. **Evaluating Each Option**:
- **Option 1: Mucus and Matrix**: This option is incorrect. Mucus is a secretion, not a connective tissue, and the matrix refers to the non-cellular component of connective tissues.
- **Option 2: Blood and Lymph**: This is the correct option. Blood is a fluid connective tissue that transports nutrients, gases, and waste, while lymph is also a fluid connective tissue involved in immune responses and fluid balance.
- **Option 3: Ground substance and Hyaluronic acid**: This option is incorrect. Ground substance is part of the matrix in connective tissues, and hyaluronic acid is a component of the ground substance, not a connective tissue itself.
- **Option 4: Collagen and Plasma**: This option is also incorrect. Collagen is a protein found in connective tissues, and plasma is the liquid component of blood, not a separate connective tissue.

4. **Conclusion**: After evaluating all the options, the two fluid connective tissues found in the human body are **Blood and Lymph**.

**Final Answer**: Blood and Lymph
