How many times a red blood corpuscle will have to pass through the heart in its journey from hepatic artery to the aorta?

Options

A. two times
B. only once
C. several times
D. four times

Explanation

To determine how many times a red blood corpuscle (RBC) passes through the heart in its journey from the hepatic artery to the aorta, we can break down the journey step by step:

### Step-by-Step Solution:

1. **Starting Point - Hepatic Artery**: The journey begins with the RBC in the hepatic artery, which carries deoxygenated blood from the liver.

2. **Travel to the Heart**: The RBC travels from the hepatic artery to the heart. It enters the right atrium of the heart. This is the first time the RBC passes through the heart.

3. **Right Atrium to Right Ventricle**: From the right atrium, the RBC moves into the right ventricle. This is still within the heart.

4. **Right Ventricle to the Lungs**: The RBC is then pumped from the right ventricle to the lungs through the pulmonary arteries. Here, it picks up oxygen and releases carbon dioxide, becoming oxygenated.

5. **Return to the Heart**: After being oxygenated in the lungs, the RBC returns to the heart, entering the left atrium. This marks the second time the RBC passes through the heart.

6. **Left Atrium to Left Ventricle**: The RBC then moves from the left atrium to the left ventricle.

7. **Final Destination - Aorta**: Finally, the RBC is pumped from the left ventricle into the aorta, which distributes the oxygenated blood to the rest of the body.

### Conclusion:
In total, the red blood corpuscle passes through the heart **two times** during its journey from the hepatic artery to the aorta.
