The heart
One continuous journey.
Two connected circuits.
The heart moves blood through the pulmonary and systemic circulations. Understanding the route helps connect its chambers, valves and major vessels.
The left ventricle pumps oxygenated blood into the aorta and through the systemic circulation.
Connect the concept
Trace the direction of blood flow before memorising individual structures. Then test whether you can recall the next step without your notes.
