Read the following statement and select the correct option
Statement 1 : Cardiac muscle of the heart is striated and has intercalated discs between its fibres (cells)
Statement 2 : It provides quick, powerful and rhythmic contractions to the heart.

Options

A. Both statement 1 and 2 correct
B. statement 1 is correct but statement 2 is incorrect
C. statement 1 is incorrect but statement 2 is correct
D. Both statements 1 and 2 are incorrect

Explanation

To determine the correctness of the statements regarding cardiac muscle, we can analyze each statement step by step.

### Step-by-Step Solution:

1. **Understanding Cardiac Muscle**:
- Cardiac muscle is a specialized type of muscle found only in the heart. It is responsible for pumping blood throughout the body.

2. **Analyzing Statement 1**:
- **Statement 1**: "Cardiac muscle of the heart is striated and has intercalated discs between its fibres (cells)."
- Cardiac muscle is indeed striated, meaning it has a banded appearance due to the arrangement of myofibrils.
- Additionally, cardiac muscle fibers are connected by intercalated discs, which are specialized junctions that facilitate communication and coordination between the cells.
- Therefore, Statement 1 is **true**.

3. **Analyzing Statement 2**:
- **Statement 2**: "It provides quick, powerful and rhythmic contractions to the heart."
- Cardiac muscle is known for its ability to contract quickly and powerfully, which is essential for maintaining blood circulation.
- The rhythmic contractions are crucial for the heart's function, allowing it to pump blood in a coordinated manner.
- Hence, Statement 2 is also **true**.

4. **Conclusion**:
- Since both statements are true, the correct option would be that both Statement 1 and Statement 2 are correct.

### Final Answer:
Both Statement 1 and Statement 2 are correct.
