Contraction of right ventricle
WebThese signals cause different parts of your heart to expand and contract. The expansion and contraction control blood flow through your heart and body. Appointments … WebSpecifically, the right atrium receives deoxygenated blood from the body via the superior and inferior vena cava, while the left atrium receives oxygenated blood from the lungs via the pulmonary veins. The atrial musculature contracts in a coordinated manner to push blood into the ventricles, which then pump the blood out to the rest of the body.
