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