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: -Blood that needs oxygen flows from your body into the right atrium. It then flows through the tricuspid valve to the right ventricle. The right ventricle pumps the blood through the pulmonary valve and into your lungs, where it picks up oxygen. The oxygen-rich blood then flows to the left atrium.
Detailed explanation-3: -Blood first enters the heart’s right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.
Detailed explanation-4: -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.
