Tricuspid Valve
A valve in the heart between the right atrium and right ventricle that prevents backflow of blood during ventricular contraction.
Mitral Valve
A valve in the heart that lies between the left atrium and left ventricle, ensuring one-directional blood flow within the heart.
Atria Contracting
The phase of the cardiac cycle where the atria of the heart contract to move blood into the ventricles.
