Which valve prevents backflow from the left ventricle to the left atrium?
Select the correct option:
Solution
Incorrect! Answer:
Mitral (bicuspid) valve
- Heart Anatomy: The heart has four chambers and specific valves to ensure one-way blood flow.
- Left Side: Blood moves from the Left Atrium to the Left Ventricle.
- Atrioventricular (AV) Valve: The valve between these two chambers is the Mitral valve (also known as the Bicuspid valve).
- 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.
- Right Side: The Tricuspid valve serves a similar function on the right side of the heart.
