What's included in the illustration
Four Chambers
| Chamber | Position | Blood type | Wall thickness |
|---|---|---|---|
| Right Atrium (RA) | Upper right | Deoxygenated (blue) | Thin |
| Right Ventricle (RV) | Lower right | Deoxygenated | ~3–5 mm |
| Left Atrium (LA) | Upper left | Oxygenated (red) | Thin |
| Left Ventricle (LV) | Lower left | Oxygenated | ~10–12 mm |
Four Valves
- Tricuspid Valve (TV) — between RA and RV; 3 leaflets with chordae tendineae and papillary muscles
- Mitral Valve (MV) — between LA and LV; bicuspid (2 leaflets)
- Aortic Valve (AV) — between LV and ascending aorta; 3 semilunar cusps
- Pulmonary Valve (PV) — between RV and pulmonary trunk; 3 semilunar cusps
Coronary Arteries
- LMCA → bifurcates into LAD and LCx (left coronary system, red)
- LAD runs down the anterior interventricular groove to the apex
- Diagonal Branch (LAD branch) supplies the anterolateral LV
- Left Circumflex (LCx) runs in the left AV groove; gives off Obtuse Marginal (OM)
- RCA runs in the right AV groove; gives off Acute Marginal (AM) and terminates as PDA (posterior descending artery)
Other structures labeled: SVC, IVC, ascending aorta, pulmonary trunk, right and left pulmonary veins, interatrial septum with fossa ovalis, interventricular septum, chordae tendineae, papillary muscles, apex.
