The blood vessel which supplies oxygenated blood to cardiac tissue is

Options

A. coronary artery
B. coronary vein
C. cornoary sinus
D. pulmonary vein

Answer

To determine the blood vessel that supplies oxygenated blood to cardiac tissue, we can analyze the options provided:

1. **Understanding Coronary Circulation**: The question pertains to coronary circulation, which is the flow of blood specifically within the blood vessels of the heart muscle (myocardium).

2. **Evaluating the Options**:
- **Coronary Artery**: This vessel is responsible for delivering oxygenated blood to the myocardium. Therefore, it is a strong candidate for the answer.
- **Coronary Vein**: This vessel drains deoxygenated blood from the myocardium back to the heart chambers, so it does not supply oxygenated blood.
- **Coronary Sinus**: This is a collection of veins that gathers deoxygenated blood from the myocardium and returns it to the right atrium. It does not supply oxygenated blood.
- **Pulmonary Vein**: This vessel carries oxygenated blood from the lungs to the heart but does not supply blood to the cardiac tissue itself.

3. **Conclusion**: Based on the analysis, the correct answer is the **Coronary Artery**, as it is the vessel that supplies oxygenated blood directly to the cardiac tissue.

**Final Answer**: The blood vessel which supplies oxygenated blood to cardiac tissue is the **Coronary Artery**.
