Detailed explanation-1: -Both the superior vena cava and inferior vena cava empty blood into the right atrium. Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs.
Detailed explanation-2: -Your inferior vena cava and superior vena cava are both on your heart’s right side. Your right and left innominate (or brachiocephalic) veins merge to form your superior vena cava. Your superior vena cava is next to the right side of your sternum and goes into your right atrium, where all the oxygen-poor blood goes.
Detailed explanation-3: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
