How Blood Flows Through a Healthy Heart - Anatomy & Physiology Guide #1821083 (License: Personal Use)

This educational diagram details the complete circulatory pathway through a healthy human heart: deoxygenated blood enters via the superior and inferior vena cava into the right atrium, passes through the tricuspid valve to the right ventricle, then is pumped to the lungs via the pulmonary artery. Oxygenated blood returns via pulmonary veins to the left atrium, flows through the mitral valve into the left ventricle, and exits through the aorta to systemic circulation. Key structures-including the aortic and pulmonary valves-are clearly labeled to reinforce understanding of cardiac function.

Used in medical education, biology textbooks, health websites, and patient education materials to explain cardiac physiology; matches user intent for learning heart anatomy, preparing for exams, or understanding cardiovascular health basics.
