Which one of the following circulation is not a type of systemic circulation?

Options

A. Coronary circulation
B. Hepatic portal circulation
C. Pulmonary circulation
D. Renal circulation

Answer

**Step-by-Step Solution:**

1. **Understanding Systemic Circulation**: Systemic circulation refers to the part of the cardiovascular system that carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart. It is responsible for supplying blood to all tissues of the body.

2. **Identifying Types of Circulation**: There are various types of circulation in the body, including systemic circulation, pulmonary circulation, and coronary circulation.

3. **Analyzing the Options**: The question asks for a type of circulation that is not systemic circulation. We need to evaluate the options provided.

4. **Evaluating Coronary Circulation**: Coronary circulation specifically refers to the flow of blood to and from the tissues of the heart (myocardium). Since this circulation is limited to the heart itself and does not supply blood to the rest of the body, it does not qualify as systemic circulation.

5. **Conclusion**: Based on the analysis, the correct answer is that **coronary circulation is not a type of systemic circulation**.
