Answer:
The right atrioventricular valve (tricuspid) regulates the opening between the <u>right atrium</u> and the <u>right ventricle</u>.
Explanation:
Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.
