Diagram of the heart illustrating an atrioventricular canal defect. The heart chambers are labeled: right atrium (RA), right ventricle (RV), left atrium (LA), and left ventricle (LV). Blood flow is shown with arrows, indicating mixing of oxygen-rich (red), oxygen-poor (blue), and mixed blood (purple) through the defect. The aorta (AO) and pulmonary artery (PA) are marked, emphasizing the altered pathways. Color-coded sections highlight where the defect allows blood to improperly flow between compartments, affecting circulation efficiency.
