Question

Which valve prevents backflow from the left ventricle to the left atrium?

RankGuru · Accepted Answer

1. **Heart Anatomy**: The heart has four chambers and specific valves to ensure one-way blood flow.
2. **Left Side**: Blood moves from the Left Atrium to the Left Ventricle.
3. **Atrioventricular (AV) Valve**: The valve between these two chambers is the **Mitral valve** (also known as the **Bicuspid valve**).
4. **Function**: When the left ventricle contracts to pump blood into the aorta, the mitral valve closes tightly to prevent blood from leaking back into the left atrium.
5. **Right Side**: The **Tricuspid valve** serves a similar function on the right side of the heart.
