During ventricular systole

Options

A. oxygenated blood is pumped into the aorta and deoxygenated blood is pumped into the pulmonary artery
B. oxygenated blood is pumped into the pulmonary artery and deoxygenated blood is pumped into the aorta
C. oxygenated blood is pumped into the aorta and deoxygenated blood is pumped into the pulmonary vein
D. oxygenated bloos is pumped into the pulmonary vein and deoxygenated blood is pumped into the pulmonary artery.

Answer

### Step-by-Step Solution:

1. **Understanding Ventricular Systole**:
- Ventricular systole is a phase of the cardiac cycle where the ventricles of the heart contract. This contraction occurs simultaneously in both the left and right ventricles.

2. **Function of the Left Ventricle**:
- During ventricular systole, the left ventricle contracts and pumps oxygenated blood into the aorta. The aorta is the main artery that carries oxygen-rich blood to the rest of the body.

3. **Function of the Right Ventricle**:
- At the same time, the right ventricle contracts and pumps deoxygenated blood into the pulmonary artery. The pulmonary artery carries this deoxygenated blood to the lungs for oxygenation.

4. **Conclusion**:
- Based on the functions of the left and right ventricles during ventricular systole, we can conclude that the correct statement is that during this phase, oxygenated blood is pumped into the aorta from the left ventricle, and deoxygenated blood is pumped into the pulmonary artery from the right ventricle.

5. **Identifying the Correct Option**:
- Therefore, the correct answer to the question is **Option A**: "Oxygenated blood is pumped into the aorta and deoxygenated blood is pumped into the pulmonary artery."
