While I can't draw a diagram, I can describe the sequence of blood flow through the circulatory system. Blood is pumped from the heart's left ventricle into the aorta, distributing oxygen-rich blood to the body. It returns deoxygenated blood through veins to the right atrium, flows into the right ventricle, and is then pumped to the lungs via the pulmonary arteries for oxygenation. Finally, the oxygenated blood returns to the left atrium, completing the circuit.
