Human Heart: Double Circulation Pathway — A Visual Explainer
A single infographic tracing how blood moves through the heart's four chambers, valves and major vessels — showing why one complete circuit is actually two separate loops through the heart.
📌 Revision Pointers
Right heart (Pulmonary circuit, in): Right Atrium → Tricuspid Valve → Right Ventricle → Pulmonary Valve → Pulmonary Artery → Lungs
Left heart (Pulmonary circuit, out): Lungs → Pulmonary Vein → Left Atrium → Bicuspid (Mitral) Valve → Left Ventricle → Aortic Valve → Aorta → Body
Double Circulation: blood passes through the heart TWICE per complete round trip — once via the Pulmonary Circuit, once via the Systemic Circuit
Follow the deoxygenated pathway (blue) from the body through the right heart to the lungs, and the oxygenated pathway (red) from the lungs through the left heart back to the body.
