Contraction of the right ventricle causes:

Explanation:
Contraction of the right ventricle sends blood to the lungs through the pulmonary circulation. When the right ventricle contracts, blood is ejected into the pulmonary trunk and then the pulmonary arteries, carrying deoxygenated blood to the lungs for gas exchange. This pathway is distinct from the systemic circulation, which is driven by the left ventricle to the entire body; coronary circulation supplies the heart muscle itself; and cerebral circulation refers to blood flow to the brain.
