The wall of the internal organs such as blood vessels, stomach and intestine contains which type of muscle tissue?

Options

A. Smooth muscle fibre
B. cardiac muscle Fibre
C. Skeletal muscle fibre
D. Neural tissue

Answer

### Step-by-Step Solution:

1. **Identify the Question**: The question asks about the type of muscle tissue found in the walls of internal organs such as blood vessels, stomach, and intestine.

2. **Recall Muscle Tissue Types**: There are three main types of muscle tissues in the human body:
- **Skeletal Muscle**: This type is attached to bones and is under voluntary control.
- **Cardiac Muscle**: This type is found in the heart and is involuntary.
- **Smooth Muscle**: This type is found in the walls of internal organs and is also involuntary.

3. **Analyze the Organs Mentioned**: The question specifies blood vessels, stomach, and intestine. These organs are part of the internal organ system and are not under voluntary control.

4. **Determine the Correct Muscle Type**:
- **Skeletal Muscle**: Not applicable as it is associated with bones.
- **Cardiac Muscle**: Not applicable as it is specific to the heart.
- **Smooth Muscle**: This is the type of muscle that lines the walls of internal organs, including blood vessels, stomach, and intestine.

5. **Conclude the Answer**: Based on the analysis, the walls of the internal organs such as blood vessels, stomach, and intestine contain **smooth muscle fibers**.

### Final Answer:
The wall of the internal organs such as blood vessels, stomach, and intestine contains **smooth muscle fibers**.
