Asked by Kayla

The tricuspid valve is closed:

A. during the rapid filling of the ventricles

B. when the mitral valve is closed

C. while the atria are contracting

D. during the ejection of blood from the ventricles


I think the answer is A but not completely sure.

How can the blood go from the atriums to the ventricles, if the tricuspid valve is closed? However, I think both B and D are correct. If blood is being ejected from the ventricles, both the mitral valve and the tricuspid valve need to be closed to prevent blood from returning to the atria.
