Contraction of the right ventricle causes:

Explanation:
Contraction of the right ventricle ejects blood into the pulmonary circulation. When the right ventricle squeezes, blood is pushed through the pulmonic valve into the pulmonary trunk and then into the pulmonary arteries toward the lungs for oxygenation. This pathway is separate from the left side of the heart, which handles systemic circulation, and from filling events that occur during relaxation. So the key idea is that the right ventricle’s squeeze sends deoxygenated blood to the lungs for gas exchange.
