The mitral valve separates the left upper chamber (left atrium) and
left lower chamber (left ventricle) of the heart. The mitral valve is formed
from two downward-facing flaps.
When the heart pumps,
blood forces the flaps open, and blood flows from the left atrium to the left
ventricle. Between heartbeats, the flaps close tightly so that blood does not
leak backward through the valve.
