Valves — they ensure one-way blood flow through the heart.
Briefly:
- Atrioventricular valves: tricuspid (right AV) and mitral/bicuspid (left AV). Chordae tendineae and papillary muscles prevent prolapse into the atria during ventricular contraction.
- Semilunar valves: pulmonary (right ventricular outflow) and aortic (left ventricular outflow). They prevent backflow into the ventricles during relaxation.
Clinical relevance: valve dysfunction can cause regurgitation (insufficient closure) or stenosis (narrowing), affecting cardiac output.
