Which part of the heart prevents the backflow of blood from ventricles to atria?
easy Q2 of 15
Step-by-Step Solution
Step 1: Understand heart valve functions
The heart has valves that ensure one-way blood flow and prevent backflow.Step 2: Identify valves between atria and ventricles
Atrioventricular valves (tricuspid and mitral valves) prevent blood from flowing back into atria when ventricles contract.Final Answer:
Atrioventricular valves → Option BQuick Check:
Valves preventing backflow to atria = Atrioventricular valves ✅
Quick Trick: AV valves separate atria and ventricles.
Common Mistakes:
MISTAKES- Confusing semilunar valves which prevent backflow from arteries to ventricles.
