WebThe Walls of the Heart. The muscular walls of the atria are thinner than those of the ventricles. When the atria contract, the thin muscular walls do not generate much pressure, but enough to force blood down into the ventricles, through the atrioventricular valves. In contrast, the walls of the ventricles are thicker and more muscular.

WebIntracardiac shunting occurs when cardiac blood flow takes a shortcut within the heart. This is the result of a hole in the walls that normally separate arterial (high oxygen) from venous (low oxygen) blood.
