The human heart generates enough pressure during systole (contraction) to propel blood several meters if not contained within vessels. At peak contraction, arterial pressure can reach around 120 mmHg in healthy adults. The muscular left ventricle pumps oxygenated blood throughout the body with remarkable force and efficiency, sustaining life with roughly 100,000 beats per day. This biological pump demonstrates the extraordinary strength and endurance of cardiovascular physiology. Important Detai

The tricuspid valve controls blood flow between the right atrium and right ventricle. It opens during diastole to let deoxygenated blood fill the ventricle, and closes during systole to prevent backflow. It’s made up of three leaflets supported by chordae tendineae and papillary muscles, which prevent the valve from inverting during contraction. This 3D animation shows the tricuspid valve in motion — seen from inside the beating heart. Based on SciePro’s 3D anatomy model. Available for B2B licen

The mitral valve regulates blood flow between the left atrium and left ventricle — allowing oxygen-rich blood to enter the heart’s main pumping chamber. During diastole, the valve opens to let blood flow into the ventricle. During systole, it closes tightly to prevent backflow into the atrium. Its two leaflets are anchored by chordae tendineae and papillary muscles, which prevent valve prolapse under pressure. This 3D animation shows the mitral valve in motion — guiding blood through the heart.
