Why is that blood flows only in 1 direction

Answers

Medical Definition of Bicuspid valve

ExplanationIt permits blood to flow one way only, from the left atrium into the left ventricle This valve is more commonly called the mitral valve because it has two flaps (cusps) and looks like a bishop's miter or headdress.

It's because there are openings in the walls that separate them. these openings are called valves because they open in one direction like trapdoors to let the blood pass through. then they close, so the blood cannot flow backwards in to the atria.
