  • Atrioventricular valve

    Either of two valves in the heart through which blood flows from the atria to the ventricles. The left atrioventricular valve is the mitral valve; the right, the tricuspid valve. The bicuspid (mitral) and tricuspid valves located between the atria and ventricles. Valves situated between the upper chambers (atria) and the lower chambers (ventricles) of…

  • Atovaquone

  • Atomic mass
