What happens to the heart valves during systole?
The valves open to allow blood to flow forward and then close tightly.
The valves remain closed to prevent blood flow.
The valves open to allow blood to flow backward.
The valves do not change position.
What is the purpose of the heart valves during diastole?
To open and allow blood to flow backward.
To remain closed and ensure blood doesn't flow backward.
To open and allow blood to flow forward.
To close and prevent blood from entering the heart.
What is Valvular Stenosis?
The valve becomes stiff or narrowed, restricting blood flow.
The valve doesn't close properly, causing blood to leak backward.
A valve bulges backward into the atrium when it should be closed.
