Question

Which part of the heart contracts to send the oxygenated blood to the rest of the body?

Answer 2

When the ventricle contracts, the blood is pushed into the pulmonary artery that branches into two main parts: one going to the left lung, one to the right lung. The fresh, oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.
