The heart is called a "double pump" because there are two functionally separate circulations

Trace the pathway of each of these circulations and include the following information: heart chambers involved, major blood vessels involved, and general areas through which the blood flows. Begin with the right atrium.
What will be an ideal response


Right atrium to right ventricle to pulmonary trunk to pulmonary arteries to lungs to pulmonary veins (pulmonary circuit pump); left atrium to left ventricle to aorta to body tissues to venae cavae (systemic circuit pump).
