- The diagram is schematic and shows the patient's anatomical right on the viewer's left.
- Cardiac output uses heart rate × stroke volume and assumes the selected values are stable averages.
- Cycle phases are simplified into filling, ventricular systole and relaxation for revision.
StudyVector-authored cardiac anatomy and calculation model using the double-circulation pathway; mapped to the reviewed curriculum topics shown below.
Accessible text description
A cutaway schematic heart shows four chambers, the vena cava, pulmonary artery, pulmonary vein and aorta. Blue and orange paths distinguish deoxygenated and oxygenated routes, with numbered flow markers and visible left-ventricular wall thickness. Every structure is also available as a native selection button with function and exam-focus text. A one-cycle timeline highlights filling, ventricular systole and relaxation without requiring animation.
