The image depicts a cross-sectional view of the human heart, highlighting the right atrium and ventricle receiving deoxygenated blood (indicated by blue arrows) from the body via the superior and inferior vena cava. Oxygenated blood (red arrow) is shown moving from the left ventricle into the aorta after passing through the mitral and aortic valves. The semilunar and atrioventricular valves are clearly illustrated to demonstrate unidirectional flow.

Used in medical education, patient brochures, and health websites to explain cardiac circulation; matches user intent for learning basic heart anatomy, preparing for exams, or understanding conditions like valve disorders or heart failure.
