The SYSTEMIC CIRCULATION transfers oxygenated blood from a central pump (the heart) to all of the body tissues (systemic arterial system) and returns deoxygenated blood with a high carbon dioxide content from the tissues to the central pump (systemic venous system).

The PULMONARY CIRCULATION is where oxygen and carbon dioxide exchange between the blood and alveolar air occurs.

The PORTAL CIRCULATION normally is only one capillary bed for each branch of a circuit, however, there are a few instances where there are two capillary beds, one after each other, in series.
