Systemic circulation takes place between which chambers of heart –

Options

A. Left atrium and left ventricle
B. Left ventricle and right atrium
C. Right atrium and right ventricle
D. Right ventricle and left atrium

Answer

**Step-by-Step Solution:**

1. **Understanding Systemic Circulation**: Systemic circulation refers to the pathway of blood flow that delivers oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart.

2. **Identifying the Chambers of the Heart**: The human heart consists of four chambers:
- Left Atrium
- Left Ventricle
- Right Atrium
- Right Ventricle

3. **Role of the Left Ventricle**: The left ventricle pumps oxygenated blood into the aorta, which then distributes it to the body. This is the starting point of systemic circulation.

4. **Role of the Right Atrium**: After the body has utilized the oxygen, the deoxygenated blood returns to the heart and enters the right atrium. This marks the end of systemic circulation.

5. **Conclusion**: Therefore, systemic circulation takes place between the left ventricle (where oxygenated blood is pumped out) and the right atrium (where deoxygenated blood returns).

6. **Final Answer**: The correct answer is **B. left ventricle and right atrium**.
