The correct pathway of blood flow through a two-circuit pathway, which is characteristic of mammals and birds, involves the heart pumping blood to the body (systemic circuit) and lungs (pulmonary circuit) in separate loops. The sequence in option A correctly describes this process: blood flows from the ventricle to the systemic circuit, then returns to the right atrium, goes to the ventricle again, and is pumped to the pulmonary circuit before returning to the left atrium.
