Question

Quizplus · Accepted Answer

The myocardium is the muscular tissue of the heart that contracts and generates the force needed to overcome the afterload of the circulation system. The other structures listed (tricuspid valve, aortic semilunar valve, AV node, and sinoatrial node) are involved in the regulation of blood flow through the heart but do not play a direct role in overcoming afterload.
