The closure of the right atrioventricular valve (also known as the tricuspid valve) is caused by the contraction of the right ventricle. When the right ventricle contracts, it creates pressure that pushes blood out of the chamber and into the pulmonary artery. The pressure also causes the valve to close, preventing any backflow of blood into the atrium.
