This educational illustration depicts a sagittal view of the human heart with color-coded structures: red for oxygenated blood pathways (e.g., pulmonary veins, left atrium/ventricle), blue for deoxygenated blood (superior/inferior vena cava, right atrium/ventricle), and orange for the aorta. Key features include the tricuspid and mitral valves, interventricular septum, and major vessels such as the pulmonary artery and aorta emerging from the top.

Used in biology and medical education websites, textbooks, or e-learning modules to teach cardiovascular anatomy; matches user intent for visual learning, homework help, or quick reference on heart structure and blood flow.
