Question

where does blood flow to once the left ventricle contracts?
aorta
inferior vena cava
pulmonary artery
superior vena cava

Explanation:

The left ventricle contracts to pump oxygenated blood out of the heart. The aorta is the main artery that receives this blood and distributes it to the rest of the body. The inferior vena cava and superior vena cava are veins that bring deoxygenated blood to the heart. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.

Answer:

Aorta
