Aortic Valve Opening Timing
edit
Suggest adaption of the timing of the opening of the aortic valve. In the current animation, it opens before ventricle myocard contracts. In reality, it opens when ventricular pressure exceeds arterial blood pressure, i.e. ventricular contraction must already be in progress.
Shading
edit
Suggest shading in a new color of high density collagen entities including the valve rings, the central body and skeleton of the heart to illuminate why the atrial Purkinge branches are anatomically and histologically shielded from influence of the ventricular Purkinge Fibers. This collagen structure is impermeable to influences of electricity and blood and effectively collects and channels all atrial electrical flow through the AV tract to the ventricular bundle branches. — Preceding unsigned comment added by 174.97.19.74 (talk • contribs) 2009-11-09T03:47:04 (UTC)
