How does blood flow through the heart starting from the right atrium to the aorta?

Blood flows through the heart starting from the right atrium, where it receives deoxygenated blood from the superior and inferior vena cava. It then moves to the right ventricle, which pumps it into the pulmonary trunk and arteries to the lungs. Oxygenated blood returns to the left atrium from the pulmonary veins, moves to the left ventricle, and is finally pumped into the aorta for systemic circulation.

The process of blood flow through the heart begins in the right atrium, which receives deoxygenated blood from the body via the superior and inferior vena cava. This blood then flows through the tricuspid valve into the right ventricle. Upon contraction, the right ventricle sends the blood through the pulmonary semilunar valve into the pulmonary trunk and arteries, directing it to the lungs for oxygenation. Oxygen-rich blood returns to the heart through the pulmonary veins into the left atrium. From there, it passes through the bicuspid (mitral) valve into the left ventricle. Finally, the left ventricle pumps the oxygenated blood through the aortic semilunar valve into the aorta, distributing it throughout the body.
