a diagram of the pathway of blood flow in the heart

The heart is a powerful, four-chambered pump that circulates blood throughout the body. Blood flow through the heart is a continuous cycle, ensuring oxygen-rich blood reaches the tissues and carbon dioxide-rich blood returns for oxygenation.---Pathway of Blood Flow1. Deoxygenated Blood Return:Blood depleted of oxygen returns to the heart via two large veins:Superior Vena Cava: Drains blood from the upper body.Inferior Vena Cava: Drains blood from the lower body.This blood empties into the right atrium.2. Right Atrium to Right Ventricle:From the right atrium, blood passes through the tricuspid valve into the right ventricle.The tricuspid valve ensures one-way flow, preventing backflow.3. Pulmonary Circulation:When the right ventricle contracts, blood is pumped through the pulmonary valve into the pulmonary arteries.The pulmonary arteries transport blood to the lungs, where carbon dioxide is exchanged for oxygen.4. Oxygenated Blood Return:Oxygen-rich blood returns to the heart via the pulmonary veins.It enters
