Vein Valve Anatomy Diagram - Blood Flow Mechanism Explained #19906 (License: Personal Use)

This medical illustration depicts a longitudinal cutaway of a vein, highlighting the bicuspid valve structure embedded in the vessel wall. The valve flaps (cusps) are shown open under forward blood pressure, with a blue arrow indicating normal antegrade flow; surrounding endothelial cells are rendered in yellow hexagons. When pressure reverses, the cusps coapt to block retrograde flow-critical for venous return against gravity.
