Mammalian Heart¶

Use this interactive to connect chamber layout, named valves and the cardiac cycle in one schematic view.

What This Diagram Does Not Show¶

• This is a simplified schematic, not a literal anatomical section or a dissection-accurate drawing of heart tissue and proportions.
• The chamber shapes and vessel positions are simplified to keep layout, valve position and pressure-driven one-way flow clearer.
• Different textbook and exam diagrams often draw the same heart differently, so the aim is to transfer the same underlying plan and phase sequence to unfamiliar diagrams rather than memorise one exact picture.
