BIOLOGY
Asked by Audrey

What mechanisms are in place to prevent the blood from flowing in the wrong direction through the heart?

There are 4 valves in the heart called the Mitral valve, and the tricuspid valve. These prevent blood flow from the atria to the ventricles. There are two others called the aortic valve and the pulmonary valve. These valves are equally important controlling blood flow out of the heart from the ventricles.
