[8] Moreover, the coronary sinus returns deoxygenated blood from the myocardium to the correct atrium. The blood collects in the ideal atrium. When the correct atrium contracts, the blood is pumped throughout the tricuspid valve into the right ventricle. As the correct ventricle contracts, the tricuspid valve closes as well as blood is pumped to the pulmonary trunk from the pulmonary valve.
