Functional Anatomy of the Heart
Move beyond basic chambers and diagrams to understand how cardiac architecture drives pressure, flow, and electrical signaling. Learn to connect valve structure to heart sounds, ventricular geometry to pumping mechanics, and coronary maps to ischemia risks.
Like Duolingo, but for Functional Anatomy of the Heart. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Deciphering the Mechanical Pump and Tracing Conduction and Perfusion. It assumes you already know the basics.

Key ideas in Functional Anatomy of the Heart
- Closure sounds result from sudden deceleration of moving blood colliding with tensed valves.
- Vibrations in the valve leaflets and adjacent ventricular walls generate the audible sound wave.
- Atrioventricular valves rely on chordae tendineae and papillary muscles to avoid prolapse.
- Semilunar valves lack chordal tethers and seal purely through back-pressure filling their cusps.
- Ventricular pressure exceeding atrial pressure closes AV valves, initiating isovolumetric contraction.
- Aortic pressure exceeding ventricular pressure closes semilunar valves, beginning isovolumetric relaxation.
- Stenosis produces systolic ejection murmurs as stroke volume forces through a narrowed opening.
- Regurgitant murmurs arise when closed valves fail to seal against peak chamber pressure gradients.
- Turbulent acoustic vibrations propagate downstream along the directional trajectory of blood flow.
- Auscultation sites target downstream thoracic windows rather than surface valve anatomy.
- Subepicardial and subendocardial fibers spiral in opposite directions across the ventricular wall
- Opposing fiber directions produce a torsion or wringing motion that starts at the apex
- Apex-to-base wringing pulls the base down and expels blood upward toward the great arteries
- The left ventricle forms a thick cylinder that generates high pressures against systemic vascular resistance
- The right ventricle forms a thin crescent pocket designed to displace volume into low-resistance pulmonary vessels
- The right ventricle empties using a peristaltic, bellows-like contraction against the septum

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Functional Anatomy of the Heart the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When blood crashes against closed valves, what actually creates the sound wave a stethoscope picks up?
